Product Description
4 Gas H2S CO CH4 O2 Calibration Gas – 60L Cylinder
This four-gas calibration mixture allows technicians to verify detector response in oxygen-deficient and combustible atmospheres using one portable cylinder. The reduced oxygen concentration is ideal for confirming alarm activation during routine bump testing and safety checks.
