Product Description
Custom 4 Gas H2S CO CH4 O2 Calibration Gas – 116L Cylinder
This custom four-gas calibration mixture is produced to match specific detector sensor configurations and alarm setpoints. The standard atmospheric oxygen concentration allows verification of toxic and combustible sensors without simulating oxygen-deficient environments.
Ideal for programs requiring consistency between manufacturer test specifications and field calibration procedures.
