DigiSens ORP T° Sensor

Oxygen/Reduction Potential and Temperature sensor.


  • Urban waste treatment (inlets, aeration basins, outlets)
  • Treatment of industrial effluent (process optimisation for nitrifying/denitrifying)
  • Deodorisation channels


The electrolyte “PLASTOGEL®” of the sensor communicates directly with the external environment without a capillary or porous membrane. There is no risk of clogging or reference diffusing.
Temperature: Measures via NTC Thermistor.


The sensor connects to any type of logger, transmitter, remote management system or PLC with a Modbus RS485 input. Thanks to sensor indexing, over 200 sensors can be connected to a logger.
Resistant to interference: Sensor pre-amplification and digital signal processing. All data regarding the calibration is saved directly to the sensor.


“Delrin®” handle ensures the mechanical strength of the sensor and the sealing of the cable.
Compact, robust and lightweight, the sensor can be portable or permanently installed.
