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.
