Methane Gas Detection & Sensors
Methane (Hydrocarbon) is an odorless gas with the chemical formula of CH4. Methane is flammable and combustible with oxygen. Methane is one of the primary components of natural gas, so it is readily found in the environment and used in a diverse range of applications. Methane has a lower explosion limit of 5.0%.
Since methane has no color or odor but can seep in through cracks in the floor, combustible gas detector is essential for any plant or refinery where methane is present. Count on PemTech’s comprehensive line of combustible gas detectors to keep employees safe and operations running smoothly. Our PT295 combustible gas sensor comes in a flame proof enclosure and has a 316 stainless steel sensor head assembly. Other features include a fully programmable alarm relay, LED display and 24 VDC power.

Gas Detector Model
PEL - A Permissible Exposure Limit (PEL) is the maximum amount or concentration of a chemical that a worker may be exposed to under OSHA regulations.
STEL - A Short-Term Exposure Limit (STEL) is the acceptable average exposure over a short period of time, usually 15 minutes as long as the time-weighted average is not exceeded. STEL is a term used in occupational health, industrial hygiene and toxicology.
TWA - Time Weighted Averages are an average value of exposure over the course of an 8 hour work shift.
