SPAN GAS FOR MULTIPOINT CALIBRATION
Some applications, such as EPA monitoring, require a multipoint calibration procedure
where span gases of different concentrations are needed. We recommend using a bottle
of calibrated CO gas of higher concentration in conjunction with a gas dilution calibrator
such as a Teledyne API’s T700. This type of calibrator precisely mixes a high
concentration gas with zero air (both supplied externally) to accurately produce span gas
of the correct concentration. Linearity profiles can be automated with this model and run
unattended over night.
