Calibration gas is used to calibrate your gas detector every 6 to 12 months to ensure accuracy. Over time gas sensors degrade. The only way to ensure accuracy is to perform gas calibration which involves exposing your gas detector to the respective traceable NIST calibration gas. Calibration gas bottles also require a gas regulator to function. We also have Bump Gas that is also recommended. Alternatively, we offer gas calibration service for your single gas detector or 4 gas meter. See our YouTube Playlist of our Calibration Gas.
