____________________________________________________________________________________________________________

· It is a digital fluorimetric oxygen sensor
· It is a digital sensor with predictive diagnostic function that converts the analog signal directly to
  digital signal
· Data is stored
in the sensor interface
· 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
                                                 · Data can be
transmitted over short distances or long distances
                                                 · The measured
value is stable and reliable
                                              · Measuring range:
0-50mg/L; Measuring accuracy: ±0.1mg/L; Resolution: 0.01mg/L
                                              · Dimensions:
Ø25*165mm
                                              · Temperature
range: 0-55℃; Measuring
accuracy: ±0.1℃; Resolution: 0.1℃
