Wireless (Bluetooth connection up to 20 m) multi-parameter air quality, temperature, humidity, air flow, lighting meter with built-in pressure difference measurement sensor: convenient menu for long-term measurements, parallel measurement of pressure difference, CO₂, CO concentration, air flow, relative humidity, temperature and lighting (measuring probes must be purchased separately).

- The pressure difference is measured by a built-in sensor, but the other parameters require a measuring probe.
- Can be supplemented with probes of many different parameters.
- Built-in memory for saving measurement data and USB connection for transferring data (measurement protocols).
- Graphical display, showing measurements of 3 different parameters at the same time (it is possible to connect 3 probes at the same time - Bluetooth probe, cable probe and K-type temperature probe).

Measuring range for pressure difference: -150...+150 hPa
Accuracy for pressure difference in the range 0...1 hPa: ±0.05 hPa
Accuracy for pressure difference in the range 1.01...150 hPa: ±(0.2 hPa + 1.5% of the measured value)
Resolution for pressure difference: 0.01 hPa

Other measurement parameters depending on the selected probe. The maximum possible temperature measurement parameters are shown below:
Measuring range for temperature (NTC probe): -40...+150°C
Accuracy for temperature (for NTC probe) in the range -40...-25.1°C and +75...+99.9°C: ±0.4°C
Accuracy for temperature (for NTC probe) in the range -25...+74.9°C: ±0.3°C
Accuracy for temperature (for NTC probe) in the rest of the range: ±0.5% of the measured value
Measuring range for temperature (for K-type probe): -200...+1370°C
Accuracy for temperature (for K-type probe): ±(0.3°C + 0.3% of measured value)
Resolution for temperature: 0.1°C

Operating temperature (for the surrounding environment): -20...+50°C
Storage temperature: -20...+50°C
Connection for probes: 1x digital probe with wire or 1x temperature (NTC) probe, 1x Bluetooth probe or Testo Smart Probe probe and 1x K-type temperature probe + built-in differential pressure measurement sensor
