  alpha-pH2000 1/2 DIN Wall Mount/Panel Mount pH/ORP Analyzer


In the ORP mode, the alpha pH 2000 is able to measure in mV or as % concentration, with independent calibration modes.  All parameters can be operated in the asymmetrical or symmetrical mode.

With a pH or ORP controller side-by-side, controllers can be operated in a master-slave operation where pH and ORP must be measured and controlled simultaneously, e.g. electroplating or swimming pool applications.  Under this setup, pH is always maintained and controlled as a first priority.  Only when pH readings are within set limits, will the ORP controller be allowed to operate the pumps. 

pH calibration is quick and easy with push buttons.  Calibration buffer sets include US, NIST and DIN standards.  Electrode condition is updated and displayed after each calibration.
