The INFWIN DigiORP is a digital ORP (oxidation-reduction potential) sensor with SDI-12 or RS485/Modbus-RTU output, integrating the ORP electrode and transmission circuit into a single compact IP68-rated probe. Output interface and cable length are configurable via ordering code - the default variant (DigiORP-ABCC002) ships with an ABS+PC shell, an ORP electrode with built-in temperature compensation, RS485/Modbus-RTU output, 4.5–28V DC supply, and a 2 m cable.

A 3/4" NPT thread makes the sensor easy to mount for submersible installation or fit directly into pipelines and tanks. Reverse power protection and built-in TVS/ESD protection are included.

Key Features

  • Integrated ORP measurement: ORP electrode and transmitter circuit combined in one compact, IP68-rated body
  • Built-in temperature compensation: Electrode includes a temperature sensor to compensate ORP readings
  • High precision and good interchangeability: Consistent readings across sensor units
  • Digital output: SDI-12 (V1.3) for universal datalogger compatibility and low-power use, or RS485/Modbus-RTU for long cable runs or multi-sensor networks, both with surge protection
  • 3/4" NPT threading: Convenient for submersible installation or mounting in pipelines and tanks
  • Low power consumption: Suited to battery-powered systems
  • Reverse power protection: Built-in TVS/ESD protection
  • Configuration utility: SensorOneSet software (RS485) or SensorOneSetSDI12 software (SDI-12) included for sensor configuration
  • ODM/OEM service available
  • Cable length: 2 m standard; custom lengths available

Applications

  • Industrial process monitoring
  • Water and wastewater treatment
  • Sewerage systems
  • Irrigation and smart agriculture
  • Aquaculture and hydroponics

Important Notes

  • Operating temperature for the sensor body is 0°C to +80°C, narrower than the ORP electrode's own −40°C to +80°C measurement range.
  • Rated for operating humidity 0–100% and pressure up to 0.2 MPa; storage conditions are −5°C to +65°C, 0–90% humidity.
  • The ORP electrode is a wear item; periodic calibration and eventual electrode replacement should be expected as part of normal maintenance.
  • Response time (under 30 s) is slower than DigiPH's (under 10 s) - allow settling time before logging readings.
  • When using Active Output mode on RS485, only one sensor should be on the network to avoid data collision.
