How the probe works

The Hanna HI-764113/10 optical DO sensing probe is based on the principle of fluorescence quenching. The sensing method features an immobilised pT based luminophore that is excited by the light of a blue LED and emits a red light. Dissolved oxygen quenches this excitation.

The major components of the probe include a blue LED for excitation, a red LED that is used as a reference light, and a photodetector. The Smart Cap™ is locked in place on the optical probe and includes the immobilised 02 sensitive luminophore with rugged insoluble black oxygen permeable protective layer.

The sensor provides accurate DO measurements over long periods of time without the need for frequent calibration.
