· ASY2151D digital DO sensor with thermistor and plug-in connection, plastic body 

• It is a digital sensor with predictive diagnostic function that converts the analog signal  directly to 

   digital signal

• Can be calibrated in the laboratory, take the field plug and display, the system automatic 

   identification, without on-site calibration of the electrode, easy to use

• No need a  DO transmitter, the sensor can output digital signal and the digital signal can be 

   transport to the computer

• The output digital signal  can be directly converted into WIFI or GPRS signal to achieve wireless 

   transmission

• Temperature range: 0-55℃; Measuring accuracy: ±0.1℃; Resolution: 0.1℃
