product name :POP-500 ORP Online Analyzer
Measurement Principle:
POP-500 ORP sensor is a combination electrode combined precious metals indicator electrode with reference electrode. Firstly measure the potential difference of working battery made up of measuring electrode and reference electrode in the solution,then use linear relation of ORP value of the measuring solution and potential of working battery to realize the ORP on-line monitoring.
Features:
- Good repeatability and stablity.
- Simple cleaning and activation,quite high balance speed.
- Optional analog-digital conversion module to achieve digital signal output,high anti-jamming capacity and far transmission distance.
- Optional analog-digital conversion module to achieve standard digital signal output（RS485）,can achieve integration and networking with other equipment without controller.
- Quick and easy field installation,adopting terminal connection.
Applications:
- ORP monitoring of tap water,municipal sewage and surface water and etc.
- ORP monitoring of industrial process water and in wastewater treatment process.
