Oxidation Reduction Potential (ORP) is a measurement of sanitizer effectiveness in water. ORP is an electronic measurement in millivolts (mV) of the ability of a chemical substance to oxidize or reduce another chemical substance. The output signal can be RS485, Analog Voltage or Analog Current. The sensor is applicable for industrial, water processing, sewerage system, irrigation, smart agriculture etc.
■ ORP measurement
■ Output Interface with RS485, Voltage, Current
■ High accuracy with excellent stability
■ Reverse power protection and Built-in TVS/ESD protection
