Yes. The Cation Differential pH and ORP sensors have a glass electrode that needs a 2 point calibration performed regularly. Because of the Cation Reverence electrode you must use special buffers with a constant sodium ion concentration. This calibration is needed to compensate for the change in response of the glass electrodes. These changes are normal and are caused by aging or chemical attack, and they are accelerated at higher temperatures.
The SC42 and SX42 conductivity sensors are ideal for high pressure, high temperature applications such as boiler blowdown and condensate leak detection applications.
Liquid analyzers are used for monitoring process chemistry including water quality, providing process optimization and control.
pH and ORP meters, analyzers and transmitters are used for continuous process monitoring of pH and ORP to ensure water/product quality, monitor effluent discharge, batch neutralization, pulp stock, scrubbers, cooling towers, chemical, water/wastewater treatment and many other applications.
Process analyzers are used to determine the chemical composition or physical properties of substances involved in industrial processes.
