Description
eCHEM pH immersion-sensor digital with M12 cable.
Robust digital pH sensor for operation on TriBox controllers. Digital communication ensures safe and trouble-free signal transmission from the sensor to the controller. The high-quality gel pH electrode has a porous HDPE diaphragm and is insensitive to dirt, making the sensor ideal for wastewater applications. TpH is available with a 10 m or a 2 m fixed cable.
