The Evolution of Gas Detectors

Portable multigas detection instruments are widely relied upon to protect users from the hazards of toxic and combustible gases. For many applications, typical sensor configuration is combustible gas, carbon monoxide, hydrogen sulfide and oxygen deficiency/enrichment, also known as the big four. Detection of the big four most commonly occurs in industrial applications such as oil/gas/petrochemical, chemical, utilities, steel, general manufacturing and the fire service.
