Provides differential ORP/REDOX measurement with no field calibration required. The ORP/REDOX sensor can be connected directly to a PLC(Programmable Logic Controller), and any computer can be used to display data and to customize and calibrate the sensor. The ORP/REDOX probe is offered in a variety of materials and has replaceable quad junction salt bridges. Pre-calibrated sensor heads can be replaced or exchanged with any other type of sensor without any system downtime, saving time and money.
The REDOX/ORP sensor/electrode is constructed to be exceptionally chemically resistant and mechanically strong, and has non-flowing and anti-fouling characteristics. The sensor also has a built-in pre-amplifier and universal engineering units conversion. The electrode also has universal signal conditioning electronics and interactive communications with a host computer or display interface via a range of connectivity options, including Modbus? RTU, DeviceNet, Profibus, USB, CANopen or Ethernet.
A titanium ground electrode is included to eliminate ground loop currents in the measuring electrode and an integral temperature sensor measures temperature independently.
