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.

Features of conductivity measurement
Built-in temperature compensation function and calibration standard table enable monitoring of the contamination of the cell for higher accuracy conductivity measurement.
Highly versatile, cell constants from 0.005 to 50 cm-1, two-way and four-way detectors are available.
It also supports five types of temperature detectors for accurate temperature compensation.
Performs pure water compensation in the analysis of demineralized water, steam, condensate, and boiler water. For monitoring of pure water in the pharmaceutical industry, the process liquid quality can be monitored according to the water quality standards of the USP item <645> (refer to item 645 of USP23 Article) guidance (USP).
