Bump Testing & Calibration Gas
Bump & Calibration Gas from Crowcon provides all portable and fixed gas detectors with the testing and calibration required. Gas detectors play a key part for people and plant safety so equipment cannot afford to be out of service.
Nowadays regulations are tighter, routine calibration tests are required along with daily bump testing and there is a real need for test gas. It has never been easier to buy gas as their are now gas distribution centres worldwide so there is no excuse for your gas detector to not be compliant.
Crowcon have developed a Bump Gas Spray which eliminates the cost and issues with transporting gas and regulators. Simply attach the straw onto the nozzle and spray a small amount of gas into the unit’s calibration cap. The unit will then go into alarm and show you that it is fully functional with audible and visual checks.
