DO Sensor

DO Sensor

This sensor is coated with a luminescent material. Green light from an LED is transmitted to the sensor surface. The green light excites the luminescent material. As the material relaxes it emits red light. The time it takes for the red light to be emitted is measured. Between the flashes of blue light, a red LED is flashed on the sensor and used as an internal reference. Increased oxygen in the sample decreases the time it takes for the red light to be emitted. The time measurements correlate to the oxygen concentration.

FAQ:

1.What do you mean by reference electrode?

A reference electrode is an electrode which has a stable and well-knownelectrode potential. The high stability of the electrode potential is usually reached by employing a redox system with constant (buffered or saturated) concentrations of each participant of the redox reaction.

2.What services can we get from your company?

Superior products(peculiar design,strict quality control); Factory direct sale(favorable and competitive price); Excellent services(delivery goods on time;one year warranty;post and after services); Professional business consultation.

3.What about your after-sales services ?
