Page 3: Preliminary Examination
Smart Caps (HI764113-1) for measurement of dissolved oxygen. ® The series is designed to work with the Hanna Instruments HI510 Universal Process Controller. When paired with the controller, the system provides accurate dissolved oxygen measurements auto-compensated for barometric pressure, salinity (set manually), and temperature. -
Page 4: Main Features
Main Features Principle of Operation The method is based on the principle of fluorescence quenching and features an immobilized Pt- based luminophore that is excited by the light of a blue LED and emits a red light. Dissolved oxygen quenches this excitation. -

Page 10: Wiring The Probe To The Controller
Wiring the Probe to the Controller 10. WIRING THE PROBE TO THE CONTROLLER 1. With the controller disconnected from power, run the probe cable through the conduit opening. 2. Connect the probe leads to the removable terminal connector marked PROBE. Follow the lead markings (+) positive / (–) negative to ensure correct wiring position for output leads. - Page 11 Calibration Standard Calibration Preparation • Remove probe from process. • Flush probe and cap with a jet of clean water. • Inspect for scratches or voids in cap surface. • Replace cap as required. • Shake any remaining solution off the probe. No droplets should remain on the DO sensing surface before performing the calibration procedure.
