Rs485 ORP Sensors With Replaceable Measuring Head For Sewage Or Drinking Water


Rs485 ORP Sensors With Replaceable Measuring Head For Sewage Or Drinking Water


Replaceable Measuring Head Digital ORP Sensor DRH790 is a device for measuring Oxidation-Reduction Potential (ORP) in solution, it is cost-effective, replaceable measuring head digital ORP sensor adopts separate design, allowing users to replace only the measuring head part, reducing maintenance and replacement costs. Environmentally friendly, convenient and fast, reliable and other advantages.


Digital output: The replaceable measuring head digital ORP sensor adopts digital output, which can be directly connected with modern control systems and instruments, eliminating the interference and errors that may be caused by traditional analog signal transmission.


Long life: Due to the design of the replaceable measuring head, the main part of the sensor is usually durable and long-lived, while being easy to replace, extending the service life of the entire sensor.


Anti-interference: Digital signal transmission has strong anti-interference ability, and the digital ORP sensor with replaceable measuring head shows high reliability in complex industrial environments.


In general, the replaceable measuring head digital ORP sensor is more economical, environmentally friendly and convenient than traditional sensors, and has advanced technical features, suitable for various application scenarios that require ORP value monitoring.
