Sample Inlet Port Used for Sample Line Calibration
Once you have attached the gas line as needed and selected the desired calibration source, tap OK. A
screen similar to the one shown below will be displayed.
Two types of calibrations can be performed on the NDIR sensor: Zero and Span. The Zero calibration
should be performed with a gas that has none of the measured gases in it. Ideally this would be pure
Nitrogen or Argon. The concentration of the Span calibration gas should closely resemble the gas that is
being measured. For a heat treating application measuring endothermic gas, the ideal composition
would be:
•
CO: 20%
