AMT/DO-400 intelligent dissolved oxygen sensor with RS485 communication interface and standard Modbusi protocol smart sensor. The principle of fluorescence measurement does not need to replace the dissolved oxygen film and electrolyte, the polarization time is short, the response time is fast, and the measurement is almost unaffected by dirt/flow rate. Corrosion resistant housing, built-in PT1000 temperature sensor and compensation algorithm.

Maintenance-free, no need to replace dissolved oxygen film and electrolyte;

Small drift, fast response and short polarization time;

Not sensitive to dirt, almost unaffected by flow rate;

Direct calibration in the air without zero calibration;

PT1000 temperature compensation, accuracy up to ±0.1℃;

Corrosion-resistant shell, waterproof grade P68, can work underwater for a long time;

RS485 communication interface, standard Modbus protocol, easy to integrate.
