ZWQ-INH1 Ammonia Nitrogen Sensor
ZWQ-INH1
The ZWQ-INH1 measures ammonia nitrogen concentration from 0-1000 mg/L using an ion-selective electrode, with accuracy of 10% of reading or 0.1 mg/L, whichever applies. It includes a built-in PT1000 temperature sensor for compensation and reports over RS485 Modbus RTU. MetSensor UK supplies the ZWQ-INH1 in the UK as part of the Zata IoT sensor range.
