SUP-pH5011 Water pH Sensor

The water pH sensor is a scientific instrument that measures the Hydrogen-ion activity in water-based solutions, indicating its acidity or alkalinity expressed as pH.
Feature
• Isolated power supply design, data stability, strong anti-interference ability.
• pH supports automatic/manual temperature compensation, (Automatically detect whether the temperature probe is disconnected or faulty, then switch to manual temperature compensation) The default is 25.0℃.
• Support USA/NIST/custom pH calibration solution, and user-defined ORP standard solution.
• Communication: RS485 interface*1 (Modbus RTU protocol).
Details

Introduction


The SUP-pH5011 Water pH Sensor designed by our company for the aquaculture industry, with a digital interface (RS485*1), can be used to measure changes in the pH/ORP value of the aqueous system within the range. It has a standard RS485 Modbus RTU protocol interface function, which can communicate with the host computer remotely.
