As for detector calibrated by Methane, for example, if you intend to
monitor Propane, so long as set CF @1.64 in menu of RAEGuard 3,
which appears detector just detects Propane.
If RAEGuard 3 detector is calibrated by non-Methane compounds,
when calibrating with Propane the new CF for Ethane is 1.43/1.64 =
0.87. For example, to detect Ethane with RAEGuard 3, you just set
CF is 0.87, which appears detector is monitor Ethane concentration
real-time.
