This RS485 pH sensor adopts an industrial-grade high-precision pH electrode, equipped with a built-in PT1000 temperature probe to realize fully automatic temperature compensation. It covers a full measuring range of 0-14pH, with a resolution of up to 0.01pH and stable measurement accuracy within ±0.05pH. It features a fast response speed, outputting stable data in less than 10 seconds in a flowing liquid environment, meeting the stringent requirements of real-time online monitoring. The device adopts the standard Modbus RTU communication protocol, enabling data transmission via the RS485 interface with a maximum transmission distance of up to 500 meters. It boasts strong anti-interference performance, can be directly connected to PLC, DCS systems, industrial control screens and IoT monitoring platforms, supports multi-node networking, features simple and efficient wiring, and greatly reduces system integration costs.
