ZWQ500 Multi-Parameter Water Quality Meter

ZWQ500 multi-parameter water quality meter is a portable five-in-one sensor. It can monitor PH, dissolved oxygen, conductivity, turbidity and temperature at the same time. It can also select extra COD, chlorophyll and cyanobacteria items.

Compared with traditional coastal instruments, ZWQ500 is more convenient to install. It uses RS485 interface and Modbus RTU standard protocol to communicate, with low power consumption, and supports solar power supply and wireless communication.

Multi-Parameter Water Quality Meter FAQs

What is Multiparameter water quality meter?

This multi-parameter water quality sensor allows for the measurement of main parameters including pH, ORP, conductivity, dissolved oxygen, and water temperature. The sensors are output via a single cable for easy installation and maintenance, or the data can be transmitted to the cloud via 4G wireless ICT.
