Product Description
High CO 4 Gas Calibration Gas – 66L Cylinder
This four-gas calibration mixture is designed to confirm detector response at elevated carbon monoxide alarm levels while validating hydrogen sulfide and combustible channels under normal atmospheric oxygen conditions.
The higher CO concentration supports verification of high-alarm and evacuation thresholds.
