  • Page 9: Calibration

    See Section 5.2 - Automatic Temperature Compensation See Section 5.9 - Pressure & Salinity Adjustment The Micro 600 DO will accept two % saturation calibration points; 100% using saturated air or air-saturated water, and 0% using zero oxygen solution. When 100% calibration is performed, the corresponding concentration is adjusted simultaneously.

    Micro600DO_ZI INST 1240 16/9/15 12:57 Page 10 Calibration Calibration of the concentration mode will only replace the previous concentration calibration and does not affect the % saturation calibration. To offset your % saturation reading to match another instrument, see Section 5.8 - % Saturation Offset Adjustment. New calibration values will automatically override the existing data.

Therefore, additional mg/L (ppm) calibration isn’t required in most circumstances. If desired, you can perform a calibration adjustment in mg/L (ppm) without affecting your % saturation calibration value.

    Micro600DO_ZI INST 1240 16/9/15 12:57 Page 35 Dissolved Oxygen Theory 12.0 Dissolved Oxygen Theory Dissolved Oxygen (DO) refers to the volume of oxygen that is contained in water. There are two main sources of DO in water; atmosphere and photosynthesis. Waves and tumbling water mix air into the water where oxygen readily dissolves until saturation occurs.

  • Page 36: Measurement Units

    Micro600DO_ZI INST 1240 16/9/15 12:57 Page 36 Dissolved Oxygen Theory Measurement Units One measure of DO in water is parts per million (ppm) which is the number of oxygen molecules (O2) per million total molecules in a sample. Calculating the % Saturation is another way to analyse DO levels.

Therefore, all you need to know is the temperature of the air in which the probe is placed. By consulting solubility tables for oxygen at the particular barometric pressure and salinity of the water being measured, the corresponding concentration (mg/L or ppm) can be found for air saturated water at the air calibration...
