pHG5201B online calculated pH meter

Overview

pHG5201Bonline calculated pH meter, Calculates pH from conductivity according to the German VGB guideline relating specific and cation conductivity to pH.pHG5201Bonline calculated pH meter Suitable for thermal power plant feedwater (economizer) and condensate water plus ammonia pHonlinecontinuous monitoring.

pHG5201Bonline calculated pH meter, via measurementconductivitycalculates pH, eliminates replacement of pH electrode and pH electroderequired monthlyperform calibration, this both saves pH electrode cost, and also reduces labour cost, further increases measurement accuracy and Stability.
