19.2 Meter Multiplication Factors for Sensepoint XCD-IR Propane
It is possible to apply a linear cross reference factor to the output of a sensor characterized
for propane and achieve the results shown in the graph below.
Reasonable accuracy is maintained to at least the 50% LEL equivalent values of the
cross-referred gasses.

NOTE
Honeywell Analytics recommends that users verify the accuracy of their instruments using
test gasses wherever possible. Cross-referred measurements should be used as a guide
only, not as absolute values.
Caution: These factors only apply to gas concentrations expressed in % Volume terms.
When using a linear cross reference factor the temperature compensation is
based upon propane, and there may be errors at temperatures away from the calibration
temperature.
