The HI7640-58 series are optical dissolved oxygen probes with HI764113-1 DO Smart Caps for measurements of dissolved oxygen. These probes are designed to be paired with the Hanna Instruments HI510 Universal Process Controller. When paired with the controller, the system provides accurate DO measurements auto-compensated
for barometric pressure, salinity (manually set), and temperature. Suitable for control applications in municipal and industrial wastewater treatment, where optimizing oxygen transfer is a key element, the probe can be installed directly in-line, immersed in a tank, or in a flow cell installation.
Principle of Operation:
The Smart Cap contains pre-loaded calibration coefficients that are automatically transmitted to the probe. The Cap stores data in a RFID tag. If caps are switched between probes, no information will be lost. The Smart Cap is locked in place on the optical probe and includes the immobilized 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 the measuring path. As a result, the sensor provides accurate DO measurements over long periods of time without the need for frequent calibration.
