Abstract
A gas detection system and method are provided for determining the type of gas present and the concentration of the gas in terms of a percentage of a specific level of the gas. This percentage level may be in terms of a lower explosive limit level of a combustible gas. The system generally includes a testing chamber, a detection channel apparatus, a memory for storing a plurality of gas signature tables, and a programmed controller for determining the identity and concentration level of a gas. The system and method further provide for the accurate determination of gas concentration level at very high and low concentration levels by weighted average computation.
