Description

The digital SenTix® 940 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.
Digital SenTix® pH electrodes have a built-in temperature sensor, are QSC-capable, have a memory for 10 calibrations and a stored serial number. The measured values are secured thanks to the signal processing in the sensor and electrode replacement is easy thanks to the calibration data stored in the sensor.

The SenTix® 940 is particularly suitable for the following applications:

Water & Environmental:	Industrial:
Swimming pool water Waste water, general Groundwater Lake water, surface water, sea water	Galvanic waste water Industrial waste water

The SenTix® 940 are available in various versions with different plugs:
