Gas Detection Guide
Explore our comprehensive guide to gases we detect, including health effects, common sources, and recommended detection solutions.
Toxic Gases
Detection solutions for toxic gases including carbon monoxide, nitrogen dioxide, hydrogen sulfide, ammonia, and chlorine. Protect workers from acute poisoning and chronic exposure.
Carbon Monoxide
Colorless, odorless toxic gas produced by incomplete combustion
Nitrogen Dioxide
Reddish-brown toxic gas with a pungent odor
Hydrogen Sulfide
Colorless gas with a characteristic rotten egg smell
Ammonia
Colorless gas with a pungent, suffocating odor
Chlorine
Yellow-green gas with a strong, suffocating odor
Ozone
Pale blue gas with a distinctively pungent smell
Nitric Oxide
Colorless gas that rapidly oxidizes to nitrogen dioxide
Sulfur Dioxide
Colorless gas with a sharp, pungent smell
Combustible Gases
Detection solutions for combustible gases including methane, propane, hydrogen, and natural gas. Prevent fires and explosions with continuous LEL monitoring.
Methane
Colorless, odorless, highly flammable gas
Propane
Colorless, odorless gas commonly used as fuel
Hydrogen
Lightest element, colorless, highly flammable
Ethanol
A volatile, flammable alcohol used in the beverage, fuel blending and pharmaceutical industry
Natural Gas
Fossil fuel primarily composed of methane
Asphyxiants
Detection solutions for simple asphyxiants including nitrogen, carbon dioxide, helium, and argon. Monitor oxygen levels to prevent suffocation in confined spaces.
A2L Refrigerants
Detection solutions for A2L low-GWP refrigerants including R-32, R-454B, R-1234yf, and R-1234ze. Meet new safety requirements for mildly flammable refrigerants.
Traditional Refrigerants
Detection solutions for HFC, HCFC, and CFC refrigerants including R-410A, R-134a, R-22, and refrigerant blends. Comply with EPA regulations and protect occupants.
