Walchem's WEC310 Series controllers measure conductivity of a solution via an encapsulated, non-contacting sensor to control replenishment pumps and/or alarms.  One or two baths may be controlled at once.  The controllers may be applied in a number of very harsh chemical control applications, including oily cleaner baths, chromates, rinse tanks, fume scrubbers and other concentrated chemicals up to a conductivity of 1000 mS/cm.

Four conductivity ranges may be selected to configure the controller over a wide range of applications.  Choice of measurement units are:  uS/cm, mS/cm, ppm and % concentration.
