CSA NRTL/C Exia T-6 approved intrinsically safe with CE mark and ATEX Certification


Versatile Calibration and Bump Testing
The MiniBump is the smallest, most lightweight and adaptive calibration gas source on the market. It is our lowest entry cost product as well as our simplest to use. It is certified to be intrinsically safe for operation on potentially explosive atmospheres. The MiniBump operates with  interchangeable generating sources providing either fixed concentration output for calibration, or ‘bump’ output to drive your detector into alarm for operational verification. Available in hydrogen sulfide, chlorine, hydrogen and hydrogen cyanide. The complete device fits into your shirt pocket and provides the equvalent of five 58 liter cylinders of gas with each generating source.



  • Calibration ready
  • Interchangeable bump / calibration gases
