RS485 Interface ORP Electrode For Wastewater Treatment Detecting

RS485 Interface ORP Electrode For Wastewater Treatment Detecting

ORP digital electrode, without instrument, can be directly connected to computer, PLC and other equipment with RS485/4-20mA signal interface for data collection and maintenance; it is convenient for users to integrate the sensor into the host computer system and the Internet of Things and other industrial control environments.

The sensor can be set through RS485 communication, such as slave address and baud rate, online calibration, factory reset, 4-20mA output corresponding range (4-20mA is optional), proportional coefficient and incremental compensation.

FAQ

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

2. How do we choose the ORP electrode when the oxidation level is high?
A: In occasions where the oxidation level is high, that is, the ORP value is high, platinum electrodes are recommended, otherwise gold electrodes are recommended. ORP measurements usually use the above two inert materials as indicator electrodes.

3. What is the wire length of the ORP electrode?
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.

4. What should ORP electrodes be used with?
A: ORP electrode cannot be used alone, it must be connected with PH/ORP controller. We have a matching controller with a suitable price, and you can choose.

5.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.
