2.4 What Gas-Tec detects
Most users will be using Gas-Tec to detect methane . The instrument is also sensitive to other hydrocarbon
gases such as propane . If other hydrocarbon gases are present, the Gas-Tec reading will reflect their
presence .
The Gas-Tec’s response to other gases differs from the reading shown for methane .
Correction factors for some common hydrocarbons are shown below:
