4-20 Output ORP/Redox Sensor WQ600
Fully encapsulated electronics 4-20 mA output Marine grade cable with strain relief Stainless steel housing
Product Description
The WQ600ORP sensor is a rugged reliable water ORP measuring device.
The sensor probe is mounted on 25' of marine grade cable, with lengths up to 500'
available upon request.
The ORP sensor output is 4-20 mA with a three wire configuration. The electronics are
completely encapsulated in marine grade epoxy within a stainless steel housing.
e. ORP (Oxidation Reduction Potential) is a measure of the oxidation activity of the water. If the oxidation activity is high it will rust a piece of iron quickly. ORP is also used as an alternative way to measure chlorine concentration, since water high in chlorine (a strong oxidizer) has a high ORP. ORP is measured as a voltage between a platinum wire and a reference electrode. As this voltage goes up, the ORP goes up. The sensor amplifies this voltage and converts it to the 4-20 mA output signal.
