The POLMON pH Logger/Controller has been specially designed for Microprocessor based flame proof and Non-flame proof applications. This instrument provides dual Relay and Analog (current) output signal in Linear or PI mode for 0 to 14 pH (user configurable through software). This Instrument can be used for measurement of pH, Temperature. It is designed as the most convenient user instrument considering user problems while measuring pH. Built in diagnostics give you specific error messages with which you can identify the problems.
