Gas detectors for when you are on the move

Portable gas detectors are ideal for confined spaces, spot leak testing, and mobile use, marked by flexibility and quality. A variety of single- or multi-gas detectors are offered in compact, lightweight designs—from simple, alarm-only units to advanced, fully configurable, and serviceable instruments.

Applications include underground utilities, vaults, boiler rooms, post-fire sites, sewers, industrial plants, industrial hygiene, first responder crews, and remote fleets.

Single gas detectors

Single gas detectors are portable gas detectors that only have the ability of detecting a single gas threat in a variety of applications and environments, from CO₂ in wineries and brewing, to phosphine fumigation in agriculture, to ammonia in refrigeration and wastewater, and many more.

When monitoring the atmosphere in a confined space, there are several important issues that need to be considered, reviewed, and managed. One of the major issues centers on air quality and what you are breathing, both prior to entry and during occupation of a confined space. You need to know what the oxygen content of the atmosphere is and whether there are explosive or toxic gases that could threaten the safety of the environment or your life. The standard four confined space gases are Combustible gas %LEL, Oxygen (O₂), Carbon Monoxide (CO), and Hydrogen Sulfide (H₂S).
