The HI764113 is the replacement probe for use with HI98198 Optical Dissolved Oxygen Meter.
Optical DO probe with built-in temperature sensor, shield and 10 m cable
Built Strong A robust ABS body and stainless steel protective guard ensure durability when measuring in tough environments. With an IP68 rating, this probe is totally sealed against water and dust. Rugged Optical Dissolved Oxygen Probe for Fresh and Saltwater Applications
Professional Level Performance The domed cap repels bubbles for better measurement sensitivity, providing a fast response time.
Minimize Hassle With no additional membranes to change and no electrolyte needed, the opdo probe is ready to work right when you need it.
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.
