ZWQ-PH1 pH Electrode Sensor
ZWQ-PH1
The ZWQ-PH1 measures pH from 0-14 using a glass electrode with ±0.1 pH accuracy and a built-in PT1000 temperature sensor for compensation. It responds in under 15 seconds and communicates over RS485 Modbus RTU. MetSensor UK supplies the ZWQ-PH1 in the UK as part of the Zata IoT sensor range.
