What are Portable Multigas Monitors?
Also known as- 4 way gas monitors, sniffers, GasTech meters, gas meters, explosive meters and gas sensors.
Portable multigas monitors are vital in protecting personnel from the hazards of toxic and combustible gases in confined space entries and potentially dangerous work environments.
Typical sensor options include detection of LEL or combustible gas (methane, LPG, hexane, propane), carbon monoxide (CO), hydrogen sulfide (H2S), and oxygen (O2) deficiency / enrichment. A long list of other gases are detectable, some specialty sensors are-
PID (Photo Ionization Detector), used measure volatile organic compounds and other gases in concentrations from parts per billion (ppb) to parts per million (ppm)
NDIR (Non-dispersive Infrared) or IR (Infrared), used to measure CO2 (0-5%), some combustible gases (LEL 0-100% and/or LEL %Vol)
