Description

Product Description

The method of monitoring ORP values in wastewater plants is to measure them using ORP Probe. ORP value refers to the redox potential and is an indicator of the redox properties in the water body. In the sewage treatment process, the ORP value can be used to monitor the redox reaction in the sewage, especially the process of the oxidation reaction, which can be used as an important indicator to judge the effectiveness and effect of the sewage treatment process.
In the process of sewage treatment, the change of ORP value can reflect the process of decomposition and oxidation reaction of organic matter in sewage, and with the progress of the treatment process, the ORP value will gradually increase, indicating that the decomposition and oxidation reaction of organic matter is gradually strengthened, and the treatment effect will gradually increase. Therefore, monitoring the ORP value of sewage plants is of great significance to ensure the quality of sewage treatment and environmental protection. Our DRH790 model Digital ORP Sensor has RS485 interface, it can be used for various applications of monitoring the ORP value.

FAQ

1.Does ORP measurement require temperature compensation?

A: ORP measurement is not temperature controlled, so the Analog Orp Sensor does not require temperature compensation. But this digital ORP sensor has a built-in temperature unit and it can detect and compensate the temperature automatically.

2. What is the wire length of the digital ORP sensor?
A: The lead wire of this electrode is 5m by default, other lengths need to be customized, contact our customer service, the price will vary with the change of length.

3.What is the advantage of digital OPR sensor?

A: The digital ORP sensor has RS485 interface, Modbus RTU, support access to standard industrial control system and the Digital PH ORP Controller.
