Carbon Dioxide (CO2) Gas Detectors
PemTech has been selling CO2 gas detectors for decades and is here to help with any questions you may have. Carbon Dioxide, or CO2, is colorless and odorless gas compound composed of one carbon atom and two oxygen atoms. Carbon dioxide is incombustible and naturally occurs in Earth’s atmosphere, but is toxic at high levels. Higher concentrations of the substance may be present at gas processing facilities and chemical plants. Carbon dioxide is heavier than air and has a PEL of 5000 ppm, which is the maximum amount that a worker may be exposed to according to OSHA regulations. PemTech’s PT605 series combustible gas detector and Carbon Dioxide gas analyzer is designed to continuously measure carbon dioxide in process gas streams.

Carbon Dioxide 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.
