Product Description
4 Gas H2S CO CH4 O2 Calibration Gas – 120L Cylinder
This four-gas calibration mixture is intended for routine bump testing where detectors must be verified without simulating oxygen-deficient atmospheres. The normal atmospheric oxygen level allows confirmation of toxic and combustible sensor response during standard readiness checks.
The large 120L cylinder supports continuous monitoring programs and multi-instrument routes with fewer cylinder replacements.
