This high-temperature resistant electrochemical probe continuously measures oxidation-reduction potential within a range of ±2000mV based on the potential difference generated between its platinum ring indicator electrode and a double-salt-bridge Ag/AgCl reference system.

Supports ±2000mV redox potential measurement, withstands operating temperature up to 135℃, stable readings under high-temperature industrial processes.
Platinum indicator electrode paired with poin ceramic sand core diaphragm and gel electrolyte, the online pH probe has low maintenance and long service life.
PG13.5 installation thread, temperature electrode optional. Selectable wiring: integral cable or separable S8/VP connectors to fit varied transmitters.
This ASR120E online ORP probe is suitable for redox monitoring in high-temperature processes, including chemical reaction tanks, sterilization processes, industrial wastewater, and high-temperature circulating water. The ORP sensor can be deployed in biotech, chemical, food&beverage industries where reliable ORP detection under elevated temperature is required.
