This sensor is coated with a luminescent material, Green light from an LED istransmitted to the sensor surface, The green light excites the luminescent materialAs the material relaxesitemits red light, The time it takes for the red light to beemitted is measured, Between the flashes of blue light, a red LED is flashed on thesensor and used as an internal reference,Increased oxygen in the sampledecreases the time it takes for the redlight to be emitted, The time measurementscorrelate to the oxygen concentration.
-Green excitation fluorescence life detection technology, no electrolyte, no inter ference, nofrequent calibration, stable and reliable measurement.
-Built-in temperature sensor automatic compensation function for water temperature.
-Support MODBUS/RS485 & 4-20mA current interface output.
