ORP-431 typeOxidation-reduction analyzer

Used to measure the oxidation-reduction potential of various solutions. It has extremely important applications in areas such as component analysis, quality monitoring, and environmental monitoring. The instrument also has the function of measuring pH value, electrode potential (mV) value, and temperature. When equipped with corresponding ion selective electrodes, multiple corresponding ion concentrations can be measured.
It can measure pH value, oxidation-reduction potential, and ion concentration using standard curve method.

PH automatic calibration effectively avoids the loss of calibration data due to misoperation.

Up to 3 sets of standard solutions can be selected to suit the usage habits of various countries.

● Electrode status and slope display, reminding electrode usage status at any time.

● Automatic endpoint locking function, eliminating human reading errors.

Intelligent switching between automatic and manual temperature compensation.

After shutdown, it can maintain calibration data for up to 10 years.
