ORP-206A Online ORP Sensor

Used in environmental water quality monitoring, acid/alkali/salt solution, chemical reaction process, industrial production process, it can meet the requirements of online ORP measurement for most industrial applications. Signal output: RS-485 (Modbus/RTU protocol). Convenient connection to third-party equipment such as PLC, DCS, industrial control computer, general controller, paperless recording instrument or touch screen. Double high-impedance differential amplifier with strong anti-interference and fast response. The patented ORP electrode, the internal reference solution oozes extremely slowly from the microporous salt bridge under the pressure of at least 100KPa (1Bar), and its forward bleed continues for more than 20 months. Such a reference system is very stable and the electrode life is extended by a factor of two compared to conventional industrial electrodes. Easy to install: 3/4 NPT pipe thread for easy submersible installation or installation in pipes and tanks. IP68 protection level.
