Introduction to paint thickness gauges

Let's talk a little about paint thickness gauges today. You need to know a few things before buying a paint thickness gauge.

What are the 3 measurement principles of
paint thickness gauges?

The best tools for measuring paint thickness over external car materials are handheld electronic equipment. There are three varieties available, and the choice is based on the part's size and form, the type of coating, and the material being painted. These devices measure using magnetic, eddy current, or ultrasonic methods.

Magnetic Principle for Steel

Steel is magnetic, hence magnetic (ferrous) gauges that use mechanical or electrical processes are used to measure the paint thickness over steel.

The components of a mechanical gauge are a graduated scale, a calibrated spring, and a permanent magnet. A measurement of thickness can be made by measuring the force needed to remove the magnet from the coated surface. Low-cost magnetic pull-off gauges offer coarse measurements that are helpful in identifying fillers under the paint, such as bondo. Detailers seldom ever use them. Usually, accuracy is within ±5%.

Eddy Current Principle for Aluminum

Utilizing an eddy current approach, paint thickness is measured over all other metals, including aluminum. A coil inside the instrument's probe creates an alternating magnetic field that causes eddy currents to form on the surface of metals when the probe is brought close to a conductive metal surface. A second coil next to it can detect the opposing electromagnetic field produced by these eddy currents.

Eddy current coating thickness gauges, which are non-ferrous, function and appear similarly to electronic magnetic gauges. In addition, they make use of a constant pressure probe and show the results on an LCD with the ability to print previously stored measurement data.

In this industry, instruments that solely use the eddy current principle are comparatively rare. Gages that combine the principles of eddy current and magnetic fields into a single device are more common. Some make measuring easier by automatically converting, based on the substrate, between different operating principles. Usually, these "combo" units cost between $400 and $1,500.

Ultrasonic Principle for Plastic

When determining paint thickness on non-metal substrates like fiberglass and plastic, an ultrasonic approach is employed. An ultrasonic transducer built into the instrument probe pulses through the coating. In order to ascertain the coating thickness, the high frequency electrical signal that is produced when the pulse bounces back from the substrate to the transducer is examined. Certain layers within a multilayer system can be measured in certain situations. The price range is from $1,800 to $4,000.

How to estimate the thickness of paint?

The surface of your car needs to be touched with a PTG in order to accurately assess the paint thickness. To acquire precise and trustworthy results, you need to follow a few simple steps.

1. Clean the surface of your car.

Cleaning the region you wish to measure is strongly advised, but washing the entire car is not necessary.

Ensure that there are no obstructions that could affect a PTG's readings, such as loose paint, corrosion, dirt, or dust. For the most part, a clean towel will do the trick; no additional cleaning solutions are required.

2. Adjust the gadget's calibration.

While it's not required to calibrate your paint thickness gauge before each usage, it's crucial to do so on a frequent basis or anytime the measuring environment changes in order to guarantee the maximum level of measurement accuracy.

Checking the manufacturer's instructions and following the on-screen directions is the simplest way to accomplish the task. Usually, "calibration kits" are part of the packaging and contain different metal parts to represent different substrates.

3. Set the gauge in place.

Set the unit of measurement (if necessary), turn on the device, and position the probe on the surface you wish to measure. Make sure the gauge is making a strong touch with the surface; if needed, lightly press down on it.

4. Determine the paint's thickness

To begin the measurement, press one of the gauge's triggers or the measurement button. Hold the PTG firmly in place, and don't take it off until the screen displays the readings.

5. Examine and evaluate the outcomes

You will soon be able to view the outcomes of your measurements.

For the best accuracy, it is advised to take many measures at various surface areas, preferably at representative locations of the car (e.g., roof, trunk, doors, depending on the objective of the measurement).

This will assist you in deciphering the readings and comprehending the distribution of paint thickness on the exterior of your car.

What paint depth outcomes are good?

While the exact value that characterizes "good" paint depth outcomes is unknown, the majority of factory paint jobs typically fall between 100 and 180 microns (µm), or 4 and 7 mills, on average.

It's customary to think about these rules:

• European cars – 100-150 microns (4-6 mills)

• American cars (USA) – 100-150 microns (4-6 mills)

• Japanese cars – 90-120 microns (3.5-4.7 mills)

How much paint should be applied to a car?

The manufacturer, measuring location, and color all affect the paint thickness of cars; it is not a constant number. The typical original car paint thickness is between 90 and 150 μm; Japanese cars typically have paint thicknesses between 95 and 105 μm, which means their paint is relatively thin; German cars typically have paint thicknesses between 110 and 130 μm; American cars have paint thicknesses between 120 and 150 μm, which means their paint is thick.

The paint thickness on the roof of the same car is often thinner here than it is elsewhere. Additionally, the door panels' paint thickness is marginally thicker than in other places. In general, there should be no more than 20 μm of variation in paint thickness across places. It is advised that users utilize paint thickness testers to take many measurements before summarizing their experience if they wish to know the precise paint thickness at different areas on an automobile.

How can I assess the used car's value with
the paint thickness tester?

The paint thickness following sheet metal work and repainting the vehicle will be more than before. The location of the repainting can be easily determined if the paint thickness is highly uneven, which can be determined by using the paint thickness tester to measure the same spot multiple times. If the paint thickness is more uniform, you will need to measure the paint thickness at other locations or compare it to the original paint thickness. Next, determine if this area has been painted over.

You can also test the paint thickness at several different points on the roof and average the results if you are unsure of the original car paint thickness's approximate range. This is so because there are seldom any impacts or other types of damage to the automobile roof. Most second hand cars still have their original paint on the tops. Measure the paint thickness in various spots based on the roof's paint thickness.

Introduction to Testo Measuring Instruments: An Overview

Testo measuring instruments have a long history dating back to 1957, when Paul Linssen and Dr. Karl-Rudolf Rommelfanger formed the company in Germany. At first, the company concentrated on creating and manufacturing electronic measurement devices, mostly for temperature measurement. A vast array of instruments for measuring different factors, including humidity, pressure, airflow, combustion analysis, thermal imaging, and more, have been added to Testo's product line throughout the years.

Let’s categorize testo measuring instruments. Now, remember that these are not all categories and not all products from testo. But this is a great short introduction of testo measuring instruments.

Hanna Instruments pH testers - bad practices to avoid

It’s not enough to simply buy and use the pH tester as you want. There are some good and bad practices on how to use and maintain a Hanna Instruments pH tester.

But don’t worry. The usage and maintenance parts are not so difficult. Any logical person can do it.

Let’s now talk about the bad practices:

1. Keeping the electrode away from moisture

Three distinct glass layers make up the detecting glass of a pH electrode: an inner, hydrated layer, and an outside, hydrated glass gel layer. The electrode's sensitivity to pH variations is provided by the hydrated layers; if the electrode is dried out, its sensitivity is significantly diminished.

Inaccurate readings, sluggish reaction times, and shifting pH levels result from this. Fortunately, by immersing the bulb and junction in a pH storage solution for at least one hour, you can usually restore a dried-out electrode. You can then calibrate the electrode and resume testing after that.

2.Cleaning the detecting glass

Your meter receives a voltage from an electrode that is dependent on the pH of the sample it is immersed in. Cleaning the pH glass may result in a static charge that taints the electrode's voltage readout. The pH value that the voltage is regarded as is also thrown off when the voltage readout is incorrect. Furthermore, the hydrated layer of glass that you have diligently developed through appropriate storage is disrupted.

Just clean the electrode with deionized or distilled water rather than wiping the electrode sensing glass.

3.Electrode storage in deionized water

Another common error made while keeping your pH electrode is to use pure water (such as deionized, distilled, or reverse osmosis).

There are almost no ions in deionized water, but there are plenty of ions in the pH electrode—both in the hydrated part of the pH sensor glass and the filling solution. The ions in an electrode will try to migrate out into the solution when it is submerged in an ion-free solution in an effort to create equilibrium. Most of the ions will eventually leave the electrode, making it ineffective. Additionally, the glass will break down far more quickly, resulting in shorter electrode lifespans.

Remove any electrode you come across that is kept in distilled or deionized water right away. Replace the fill solution if the electrode can be filled again. After changing the fill solution, calibrate and store the electrode in the storage solution.

4.Failing to clean the electrode

Accurate pH measurements can only be obtained by cleaning in addition to calibrating. This occurs as a result of deposits coating the detecting glass on the electrode. Consequently, you will not be measuring the sample alone, but the deposits as well.

Unclean electrodes might also result in a delayed response time. Even if the value seems fixed, it's actually drifting very slowly to the true value; you might even record it at that point. There could be an extremely tiny layer of scale or grease on the electrode, even if it looks clean.

5.Utilizing a worn-out or expired electrode

The glass's sensor part will deteriorate and lose some of its original responsiveness as electrodes age. Your electrode will eventually cease reacting appropriately to pH variations.

When electrodes are operating correctly, there are specific numbers connected to them. Two well-known measures that you can use to gauge the performance of your electrode are slope and offset. It is possible to ascertain these figures during calibration.

Sometimes, no matter how hard you try, the electrode just doesn't work the way you want it to. It may be time to replace the electrode if it is old.

Okay.

Now that you know some of the bad practices, are you ready to take your pH testing game to the next level?

It’s easy really.

What to look for when buying a paint thickness gauge

A paint thickness gauge is an essential tool to check whether the car you want to buy has been damaged in the past. This tool is particularly useful if you want to buy a used car because a used car has more potential to be damaged in its history.

While others may view car paint as simply cosmetic, we understand its true importance. A good gauge goes beyond aesthetics, providing you with valuable insights into the quality and durability of the paint on any vehicle. Unveil the true story behind every coat of paint and make informed decisions when buying or maintaining your car. Trust in a paint thickness gauge as a reliable tool to uncover what lies beneath the surface.

Paint thickness gauge - what is it?

A car paint thickness gauge, also known as a paint meter, is a device that allows you to measure the thickness of the paint or coating on your vehicle’s surface.

Car lovers or professionals can use it to detect repainted areas of a car.

Main measurements are in microns (µm – one millionth of a meter).

Basically, a paint thickness gauge will allow us to tell whether a car has been repaired.

Three types of paint meters

There are three main types of paint meters. The devices can be equipped with a flat, pressure or ball probe.

First, a flat probe is a basic sensor that is installed in more inexpensive paint thickness meters. It must be pressed precisely against the surface to be checked to obtain the result.

Second, a more refined solution is a paint tester with a pressure probe. It ends with a sensor that hides in the housing when pressed against the bodywork.

Third type is a paint tester with a ball probe. It provides the most accurate measurement results. It can be used to check the coating thickness on convex and concave surfaces, and not only on flat surfaces, as is the case with less advanced probes.

What is a good and “bad” paint thickness gauge?

When choosing a paint meter, opt for one that goes beyond the basics. Look for a gauge that not only detects steel and galvanized steel bodies but also aluminum bodies. Don't compromise on accuracy - go for a tester with a resolution of 1 μm, so you know exactly how thick that paint is.

And let's not forget about the probe. The type and mounting method matter! The best paint thickness gauges feature a ball probe, ensuring accurate measurements and hassle-free usage.

How to use/ check the paint thickness with a paint meter?

Know what to expect with typical paint thickness ranges, but beware of variations based on country of production or vehicle brand. Japanese or South Korean models may have thinner coatings compared to European cars, so don't be surprised by a result of 100 μm. But keep an eye out for discrepancies that exceed 40% - this could indicate a repainted part.

Don't let shady repairs go unnoticed. If your meter shows results exceeding 200-300 μm or if there's a stark difference in paint thickness between opposite sides of the vehicle, it's time to question the integrity of that paint job.

How to use a paint thickness gauge? Make sure that the car is clean. While a ball probe tester can handle dirt, a basic meter may show false results.

Place the probe perpendicularly on the car body and press lightly. You need to check the entire body of the car and the order in which items are checked does not matter much. For example, you can start with the roof, because it is an element that is relatively rarely painted.

Then you can work around the whole body of the car with the paint meter to check every essential part.

Remember, we check a given car element in several or even a dozen places. For example, we examine the door not only in the middle, but also on the pillar, upper and lower edges, and in the front and rear parts.

When is it useful to exploit a paint meter?

For example, if you’re buying a used car and are not sure about its history, you may want to measure the paint level on different body parts. Again, higher readings can signal a repaint, meaning that the car was involved in some accident or the metals were rusty.

Another case is for car detailers. Very often car detailing involves cosmetic work, so it is important to know the paint levels before doing any corrections. It will allow you or auto detailers to determine if the car’s surface contains enough clear coat to do modifications safely.

Finally, it’s beneficial to check the quality of the paint job after it’s done. With a paint meter we can easily do that. Simply use it to check panels, etc.

Testo 535 - FAQ about CO2 measuring

Testo 535 is ideal for ensuring the air quality is optimal for humans to breathe. For example, if carbon dioxide is high in a room then it can cause many health complications like fatigue, headaches and even fatality.

Let’s talk about frequently asked questions people might ask related to CO2 monitors and devices like the Testo 535.

1.How does the Testo 535 work?

It uses a CO2 infrared sensor to measure CO2 in air. The measuring device then displays the CO2 levels in parts per million (ppm) on a digital screen or through the Smart App as a second display.

2.What is considered an optimal CO2 level in air?

Of course, this is a debatable question (because every person is slightly different) but universally optimal CO2 level is generally considered to be between 400 and 1,000 ppm for indoor environments. Though, keeping the levels below 800 ppm is recommended by some experts.

3.Is CO2 dangerous or not?

Generally speaking, CO2 is not toxic but it is definitely very harmful for humans in high concentrations in closed environments.

For example, CO2 above 5,000 parts per million (ppm) can cause symptoms such as headache, dizziness, and shortness of breath. When CO2 concentrations are very high (like above 40,000 ppm) that can cause unconsciousness and even death.

4.What affects CO2 levels in air?

In general, CO2 levels tend to increase in poorly ventilated, crowded, or small spaces.

The factors that can affect CO2 levels also include the activities performed in the room (e.g., cooking, exercising, smoking), and the outdoor air quality too.
