Zetian - Model ZDO-02 -Dissolved Oxygen/Temperature Sensor
The ZDO-02 is a dissolved oxygen smart electrode using RS485 communication interface and standard Modbus protocol. It can be widely used in dissolved oxygen monitoring in water plants, surface water, aquaculture, industry and other fields.Corrosion-resistant shell, suitable for various harsh working environments;
Adopting optical method, no need to replace electrolyte, short polarization time, fast response time;
measurement is hardly affected by dirt and flow rate;
Small electrode drift, no need for zero calibration;
Built-in temperature compensation, the accuracy can reach 0.1℃;
RS485 communication interface, standard Modbus protocol, easy to integrate.
