ZDO-02 Dissolved Oxygen/Temperature Sensor
Product Overview
Message Email
The ZDO-02 Dissolved Oxygen Sensor is a kind of intelligent dissolved oxygen (OD) electrode adopting RS485 communication interface and standard Modbus protocol. It can be widely applied to dissolved oxygen monitoring in sewage plants, waterworks, surface water, aquaculture and industries, etc.

Features

With corrosion resistant shell and IP68, applicable to all kinds of poor working conditions
Adopt Optical Method without replacing dissolved oxygen membrane and electrolyte; with features of short polarization time and fast response, the measure is almost unaffected by dirt and velocity
Small drift of electrode, direct calibration in the air, dispensing with zeroing
With built-in NTC22K temperature compensation, the accuracy can reach 0.1℃.
Use RS485 communication interface and standard Modbus protocol, convenient for integration
