Collection: Gas Detectors

Portable single-gas and multi-gas detectors for confined space entry, oil and gas operations, water treatment, and industrial environments where toxic or combustible gas hazards exist. We carry detectors for hydrogen sulfide (H2S), carbon monoxide (CO), oxygen (O2), combustible gases (LEL), ammonia (NH3), and four-gas combinations from US manufacturers including MSA Safety.

Choose from maintenance-free disposable single-gas monitors with 2-year battery life for spot checks, and reusable multi-gas detectors with replaceable sensors for daily use. All comply with OSHA 1910.146 permit-required confined space requirements and are essential for pre-entry atmospheric testing.
