  • Page 100: Calibration

    Calibration Calibration adapts the device to the individual sensor characteristics. For best performance, you should always calibrate in air. Compared to water, air is a calibration medium which is easy to handle, stable, and thus safe. In the most cases, however, the sensor must be removed for a calibration in air.

    Zero Calibration Flawless, amperometric oxygen sensors have a low zero current. Therefore, a zero calibration is only recommended for measurement of oxygen traces. When a zero calibration is performed, the sensor should remain for at least 10 to 30 minutes in the calibration medium (sulfite solution or nitrogen) in order to obtain stable, non-drifting values.

  • Page 109: Ldo Calibration

    LDO Calibration Calibrating/Adjusting the SE 740 Optical Oxygen Sensor Every oxygen sensor has its individual slope (Stern-Volmer constant cvs) and its indi- vidual zero point (phase angle). Both values are altered, for example, by aging. For sufficiently high accuracy of oxygen measurement, the analyzer must be regu- larly adjusted for the sensor data (adjustment).

  • Page 110: Ldo Slope Calibration In Air

    LDO Slope Calibration in Air Automatic Calibration in Air The slope is corrected using the saturation value (100 %), similar to air saturation of water. Since this analogy only applies to water-vapor saturated air (100 % relative humidity) and often the calibration air is less humid, the relative humidity of the calibration air must also be specified.

    LDO Slope Calibration in Water Automatic Calibration in Water The slope is corrected using the saturation value (100 %) of water in equilibrium with air. NOTICE! The calibration medium must be in equilibrium with air. Oxygen exchange between water and air is very slow. Therefore, it takes a relatively long time until water is saturated with atmospheric oxygen.

    LDO Product Calibration Product Calibration (Calibration with Sampling) When the sensor cannot be removed – e.g. for sterility reasons – its slope can be determined with “sampling”. To do so, the currently measured process value is saved by the analyzer. Directly afterwards, you determine a reference value using a porta- ble meter, for example.
