The HI-98198 opdo™ is only compatible with the Hanna digital dissolved oxygen probe HI-764113.
Concentration measurements are automatically compensated for barometric pressure, temperature and salinity. Barometric pressure and temperature are automatically measured and compensated. Salinity is automatically compensated by setting manually the salinity concentration of the water being measured. The meter also has a built in application to measure and calculate BOD (biological Oxygen Demand), OUR (oxygen uptake rate), and SOUR (Specific Oxygen Update Rate).
How the probe works
The Hanna HI-764113 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 0sub2/sub 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.
