PH & ORP
PH and ORP Analyzers
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.
Obtaining accurate pH and ORP measurements from your analyzer and interpreting this data correctly is critical to ensuring product quality and making accurate predictions of sensor lifetime.
Relevant Process Solutions pH and ORP measurement solutions include 2-wire and 4-wire analyzers featuring real-time online sensor diagnostics to provide reliable results. Our pH and ORP analyzers use the latest analyzer sensor technology to improve predictive maintenance and reduce the time and costs associated with sensor maintenance and replacement, optimizing your OPEX.
Features of pH and ORP measurement
Built-in calibration standard table, with temperature compensation function and stability check function, realizes high-precision pH measurement. In addition to pH measurements, temperature and redox potential (ORP) can also be measured.
As a diagnostic function of the detector, impedance, asymmetric potential, slope, etc. are constantly measured to continuously diagnose the state of the detector such as dirt/damage of the electrode, disconnection, and lowering of the measuring liquid level. In addition, the latest five calibration results are stored to predict future maintenance and calibration timing.
