How to read a gas monitor specification

A gas monitor lists the gases it detects, the sensor type and the measuring range for each (for example 0 to 100% LEL for combustibles, 0 to 25% volume for oxygen, 0 to 100 ppm for H2S), its alarm set points, battery run time, and intrinsic safety approvals (UL or CSA Class I Division 1 marks). Calibration gas and bump-test schedules follow the manufacturer's manual.

Ratings and specifications on this page are shown as published by the manufacturer or the named standard and describe performance in that standard's test. They are not a recommendation for any task. The employer's hazard assessment decides what protective equipment a job needs. Verify details against the manufacturer's current documentation before you buy.
