Product Description
Low H2S 4 Gas Calibration Gas – 120L Cylinder
This custom four-gas calibration mixture verifies detector sensitivity at low hydrogen sulfide levels while confirming carbon monoxide and combustible sensor response under normal atmospheric oxygen conditions.
The large 120L cylinder supports continuous bump-testing routes and minimizes replacement frequency in facility monitoring programs.
