Product Description
Low H2S 4 Gas Calibration Gas – 66L Cylinder
This custom four-gas calibration mixture is engineered for detectors requiring low hydrogen sulfide verification levels. The reduced 5 ppm H₂S concentration allows confirmation of sensor sensitivity while simultaneously validating carbon monoxide and combustible channels under normal atmospheric oxygen conditions.
Used when monitoring programs require accurate response at lower toxic exposure thresholds.
