How to choose a single-gas detector
Single-gas monitors protect workers against one known hazard, most often H₂S, CO, O₂ or a specific toxic gas. Decide between maintenance-free disposable units (fixed 2–3 year life, no charging) and serviceable units with replaceable sensors and adjustable alarms. Match the sensor and alarm setpoints to the exposure limits used at your site.
