* Searchline Excel Plus & Edge will respond to most hydrocarbon gases as most do absorb IR in the required wavelengths.
** Calibration to Universal Hydrocarbon covers a range of specific but different gases within one calibration that meets
the requirements of the performance standard.
Searchline Excel Plus & Edge will respond to a wide range of Hydrocarbon Gases*:
Methane 1,2 , Ethane 1 , Propane
1 FM Performance Approved;
The default calibration is to Universal Hydrocarbon**.
Calibration to other gases is optional and should be consulted with Honeywell.
