CAUTION: Use care during servicing and use. The HI 764080 contains a glass insulator. Do not drop or handle carelessly. Probes from Hanna Instruments are shipped dry. 1. Carefully remove the cardboard shipping tube used to protect the probe during shipping. Save the tube, should the probe be stored dry again. -

The probe is polarized with a xed voltage of approximately 800 mV between Dissolved the cathode and anode. Probe polarization is essential for stable measurements. Oxygen With the probe properly polarized, oxygen is continually consumed as it passes Setup through gas permeable PTFE membrane. If polarization is interrupted, the electrolyte solution continues to be enriched with oxygen until it reaches an equilibrium with the surrounding solution. -

Salinity and Altitude Compensation Dissolved Temperature, altitude and salinity compensation are used for DO concentration Oxygen measurements (ppm or mg/L). When the water is colder, it can hold more Meter dissolved oxygen, when it is warmer it holds less oxygen. Compensation Con guration for temperature-related solubility is done automatically using the built-in temperature sensor within the DO probe and algorithms in edge... - Page 24 Dissolved 100% Saturated Calibration It is suggested to perform the slope calibration in water-saturated air. Oxygen Pour water into a small beaker. Calibration Rinse the polarized probe with clean water. Dry the probe tip and allow a few seconds for the LCD reading to stabilize (probe in air).

Page 27: Dissolved Oxygen Measurements
Oxygen is consumed during the measurement. For accurate DO measurements, Dissolved water movement of 0.3 m/s is suggested. This is to ensure that the oxygen- Oxygen depleted membrane surface is constantly measuring a representative sample. Measurements The use of a magnetic stirrer is recommended. The probe has a built-in temperature sensor. -
