The HI-7641133 optical dissolved oxygen probe (opdo®) is based on the principle of fluorescence quenching. An immobilised Pt-based luminophore is excited by the light of a blue LED and emits a red light. As oxygen interacts with the luminophore it reduces the intensity and lifetime of the luminescence. The lifetime of the luminescence is measured by a photodetector and is used to calculate the dissolved oxygen concentration.

Description
HI-7641133 Optical Dissolved Oxygen Opdo Probe
The probe is fitted with easy to use Smart Caps (HI-764113-1) which lock in place and contain pre-loaded calibration coefficients that are automatically transmitted to the probe. The Smart Cap features an immobilised O₂ sensitive luminophore with rugged insoluble black oxygen permeable protective layer.
Over time, the sensor’s optical components can age but are compensated for by using the reference signal to compensate for the measuring path. As a result, the sensor provides accurate DO measurements over long periods of time without the need for frequent calibration.
The HI-7641133 probe is compatible with the HI-6000 multiparameter system from Hanna Instruments. This modular multimeter allows you to plug-and-play modules for pH, ORP, ISE, EC and DO, providing full flexibility in measurement while saving benchtop space for laboratory and research environments.
