Product Description
4 Gas H2S CO CH4 O2 Calibration Gas – 116L Cylinder
This four-gas calibration mixture is used to confirm detector performance where oxygen deficiency and combustible hazards must be verified together. The reduced oxygen concentration activates alarm response while toxic and LEL channels are validated in a single exposure.
The 116L cylinder supports daily testing routes without frequent cylinder replacement.
