Description

The SenTix® 20-22 pH electrodes with their plastic shaft are particularly suitable for mobile (field) pH measurement. The cylindrical shape of the membrane is robust and the fiber diaphragm prevents clogging. With the gel electrolyte filling, these electrodes are low-maintenance and do not need to be refilled.
Temperature compensation is carried out either manually or via an external temperature sensor.

The SenTix® 20-22 are particularly suitable for the following applications:

Industrial:	Water & Environmental
Galvanic waste water Industrial waste water	Aquarium water Swimming pool water Waste water, general Groundwater Lake water, surface water, sea water
Cosmetics & Cleaning:
Household cleaners

The SenTix® 20-22 are available in various versions with different connections:
