Product Description
Low H2S 4 Gas Calibration Gas – 34L Cylinder
This custom four-gas calibration mixture verifies detector response at very low hydrogen sulfide levels. The 5 ppm H₂S concentration confirms early sensor activation while carbon monoxide and combustible channels are tested under normal atmospheric oxygen conditions.
The compact 34L cylinder supports portable field testing and quick safety verification before entry into hazardous areas.
