How to check the calibration and linearity of gas analysers

Calibration is the process of establishing the relationship between the output of a measurement and a known input. In common with most measuring instruments, gas analysers require calibration following installation, and then at regular intervals to check that they are performing to specification. Regular zero and span checks (known inputs)
