INFWIN DigiORP Digital ORP Sensor

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.
