Page 17: O 2 Measurement
, &&D E^ 'D 'D measurement The oxygen sensor (pos. 23) is located behind the inlet (pos. 17) of the DGM and in front of the inlet to the CO measurement chamber (pos. 02). There are two different types of oxygen sensor available for the c-DGM. The LHO sensor is suitable for measuring very accurately at low oxygen concentrations, the WLO sensor is suitable for measuring for higher oxygen concentration over a wider measuring range. -
Page 18: Tpo Measurement
, &&D E^ 'D 'D *TPO measurement When the c-DGM is used in combination with an ISD sampling device, the TPO value can be determined in a sealed product packet. The traditional Uhlig's method, whereby the DO value is multiplied by a Z factor (see Appendix I) is used to calculate the TPO value. The use of Uhlig's method is based on an oxygen balance between the oxygen dissolved in the liquid and the oxygen in the headspace volume. -

Page 48: One Point Calibration
, &&D E^ 'D 'D 7.4.2 *One point calibration LHO sensor For most applications in the low oxygen measuring range a calibration of the zero point is sufficient. To do so follow the instructions as given for the calibration with two gasses. The atmospheric pressure and the concentration of the high calibration do not have to be entered again. - Page 49 , &&D E^ 'D 'D Attention! Use only low gas flows to flush the c-DGM. Use a reducing valve while flushing the c-DGM with pressurized air and adjust the flow by means of a flow meter to 30 l/hour. Attention! For an accurate O calibration or gas inspection, the c-DGM must be at the same temperature as the gas.
