WTW SenTix® 20, 21, 21-3 or 22 maintenance-free pH electrode

WTW SenTix® 20, 21, 21-3 or 22 maintenance-free pH electrode

SenTix® 20, 21, 21-3 or 22 standard electrodes with gel electrolyte for pH measurement in laboratories and other facilities.

- Maintenance-free gel reference system throughout the life of the product.
- Economical in operation.
- Durable plastic housing.

pH level measurement range: 0...14pH
Operating temperature (for the surrounding environment): 0...+80°C

pH electrodes with gel electrolyte are ideal for measurements both in the laboratory and outside. Especially recommended for measurements in adverse conditions.

Versions:
SenTix® 20: S7 plug, AS/DIN or AS/BNC cable required
SenTix® 21: 1m cable with DIN plug
SenTix® 21-3: 3m cable with DIN plug
SenTix® 22: 1m cable with BNC plug
Electrodes do not require any maintenance, apart from occasional cleaning, so they are particularly economical.
