4-Wire ORP Analyzer
Model OR400G

Product Information

OR400G 4-Wire ORP Analyzer

The OR400G Oxidation Reduction Potential (ORP) Analyzer is suitable for large-scale plants as well as for general measurement and control applications.

The use of this converter in combination with the ORP Sensor (OR8ERG, OR8EFG, HA485, etc.) allows continuous measurement of ORP in a wide range of processes. Converter parameters can be set interactively from the front panel; real-time self-diagnostic functions ensure continued accuracy and reliability.

Various electrode washing methods are supported: ultrasonic washing, jet washing, and brush washing.
