Carbon Monoxide, also written as CO, has a few similar properties as methane because it is also colorless and odorless. Carbon monoxide is even tasteless, so a detection system is the best possible safeguard. CO is slightly lighter than air and has an LEL of 12%. Many industrial facilities have stringent requirements when it comes to detecting carbon monoxide. Pemtech’s line of carbon monoxide sensors are ideal for the oil and gas industry because we specialize in a full line gas detection products specifically for commercial use.

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.
