Liquid PH Sensor
1. Features
•Signal output: RS-485 (Modbus / RTU protocol).
•It is convenient to connect to PLC, DCS, industrial control computer, general controller, paperless recording instrument or touch screen and other third-party equipment.
•Dual high impedance differential amplifier, strong anti-interference, fast response.
•Patented pH probe, the internal reference liquid seeps out from the microporous salt bridge very slowly under a pressure of at least 100KPa (1Bar), and its positive seepage lasts for more than 20 months. Such a reference system is very stable, and the electrode life is doubled compared to ordinary industrial electrodes.
•Immersion installation, easy to install in the pipeline and tank.
•Protection grade IP68.
