OXY 70 The Future Starts Now 3. Calibration of the oxygen sensor The luminophore of the optical sensor is subject to aging and wear, so you need to calibrate it regularly in the air. 3.1 Calibration in air at 100% The ordinary calibration is made at 100% in air.
OXY 70 The Future Starts Now 3) When the reading is stable and appears icon, press the button to confirm, the display shows End and the meter enters measurement mode. Perform also Calibration in air at 100%. The calibration remains in memory even after the instrument is turned off.
OXY 70 The Future Starts Now 4. Dissolved oxygen measurement 4.1 Before starting In order to reduce measurement errors and achieve the greatest possible accuracy, observe the following rules before you begin: The sensor must be calibrated The sensor must be vertical with the membrane downwards ...
OXY 70 The Future Starts Now 4.5 Salinity compensation (manual) The salinity of the sample to be measured influences the dissolved oxygen partial pressure. For a correct measurement you must set the salinity value of the sample. If you make oxygen measurements on salt water or sea water it is important to correct the measurement by setting the salinity value indicative of the sample.
