Product Description
Low H2S 4 Gas Calibration Gas – 44L Cylinder
This custom four-gas calibration mixture allows verification of detectors requiring low hydrogen sulfide test concentrations. The 5 ppm H₂S level confirms early sensor response while carbon monoxide and combustible channels are validated under normal atmospheric oxygen conditions.
Ideal for portable testing kits where reliable low-level detection is critical.
