Specification
Performance Features

Performance characteristics:

● Signal output: RS-485 (Modbus/RTU protocol).

● Easy to connect to PLC, DCS, industrial control computer, universal controller, paperless recording instrument or touch screen and other third party equipment.

● Double high impedance differential amplifier, strong anti-interference, fast response speed.

● ORP probe, the internal reference fluid exudes very slowly from the microporous salt bridge at a pressure of at least 100 kpa (1Bar), with positive exudation for more than 20 months. This reference system is very stable, and the electrode life is longer than ordinary industrial electrode.

● Easy installation: 3/4NPT pipe thread, easy to sink or mount in pipes and tanks.

● IP68 protection grade.
