ZWQ500 Multi-Parameter Water Quality Meter
ZWQ500
The ZWQ500 is a combined probe that measures temperature, pH, conductivity, dissolved oxygen and turbidity from a single housing, with COD, chlorophyll or cyanobacteria available as factory options. It is designed for long-term unattended deployment in surface water or groundwater and reports data over RS485 Modbus RTU, with RS232, WiFi, Bluetooth or LTE also supported. MetSensor UK supplies the ZWQ500 as the official UK reseller of Zata IoT sensors.
- ✓ Five core parameters (temperature, pH, conductivity, dissolved oxygen, turbidity) in one probe body
