Crowcon Bump Tester and Gas Calibrator

With regulations driving tighter calibration routines and the requirement for daily bump testing, there is a real need for test gas. Gas detectors play a key part for people and plant safety so equipment cannot afford to be out of service.

Crowcon offer a full range of bump and calibration gas with a range of accessories for all your portable and fixed gas detector testing and calibration needs. Bump testing has always been a challenge for mobile users with the difficulties and cost of transporting gas and regulators.  

Crowcon’s Bump Gas Spray is a can that comes with a nozzle for easy testing of equipment. 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.

  • Certificate of conformity – for peace of mind, full compliance and actual gas values are shown on the cylinder
  • All cylinders come with Certificates of Analysis as standard – if you lose your certificate, Crowcon will have full traceability so we can get a copy of the certificate, giving you peace of mind.
  • Long shelf life for reactive gases – more bump and calibrations from the cylinder before it expires, therefore cost-effective and reduces waste
  • Wide range of calibration gas – the convenience of having the gas you need to calibrate or bump test your fleet

User friendly
  • Fast shipment times – you have the right gas when you need it, no down-time
