ZONEWU Submersible ORP Sensor for Water Quality with RS485 Modbus RTU Output IP68 Rating and 3/4 NPT Thread

Product Introduction:

In complex scenarios such as environmental water quality monitoring, acid-base salt solutions, chemical reaction processes, and industrial production, ORP (oxidation-reduction potential) is a core indicator for evaluating the disinfection ability and oxidation-reduction status of water bodies. The ZW-ORP-PR online ORP sensor is designed specifically for harsh industrial sites, based on RS485 (Modbus/RTU) digital output, equipped with patented electrode technology and dual high impedance differential amplifiers. With a reliable measurement range of -1500~+1500mV, resolution of 1mV, and accuracy of ± 20mV, it helps you accurately control the redox balance of water bodies 24/7.

Core Advantage:
① Patent electrode, ultra long lifespan
The internal reference solution slowly seeps out from the microporous salt bridge under a pressure of ≥ 100KPa, and the forward seepage lasts for more than 20 months. The reference system is extremely stable; The lifespan of electrodes is doubled compared to traditional industrial electrodes, significantly reducing the frequency of replacement.
② RS485 digital output, strong anti-interference
Standard Modbus RTU protocol, supporting multi-point networking, with a communication distance of up to 1200 meters. Double high impedance differential amplifier design, fast response, strong anti-interference ability, digital signal transmission is not affected by line resistance and electromagnetic effects, suitable for harsh industrial sites.
③ Durable and sturdy, with flexible installation
Fully sealed ABS/PC and alloy material, IP68 protection level, capable of long-term immersion; 3/4 NPT pipe thread supports immersion, pipeline or tank installation (requires a tilt of 15 ° or more), paired with M16-5 core waterproof connector, 5-meter cable can be customized.
④ Easy integration, worry free maintenance
Compatible with third-party devices such as PLC, DCS, industrial control computer, touch screen, etc., plug and play; One point calibration, combined with 86mV/256mV/-40mV standard solution to quickly complete calibration. low power consumption 0.2W@12V Suitable for long-term unmanned monitoring.
