ZWQ-ORP1 ORP Electrode Sensor
ZWQ-ORP1
The ZWQ-ORP1 measures oxidation-reduction potential (ORP) from -2000 to 2000 mV with ±1 mV accuracy, using a glass electrode with a 99.9% platinum sensing element and a double salt bridge design. It responds in under 15 seconds and communicates over RS485 Modbus RTU. MetSensor UK supplies the ZWQ-ORP1 in the UK as part of the Zata IoT sensor range.
