The Cal 2000 is CSA, ATEX and CE certified

The ACD MiniBump is Calibration Ready!

Gases supported:

  • CSA certified intrinsically safe.
  • Compact "shirt pocket" size.
  • Low power consumption.
  • Tracks cell usage.

The MiniBump is an ultra-small certified calibration gas instrument specifically designed for "bump" testing chlorine, hydrogen, hydrogen cyanide and hydrogen sulfide gas sensors.

Intrinsically Safe

The MiniBump is approved
by CSA NRTL/C Exia T-6.

Cost Effective

The MiniBump cal gas generator uses only two "AA" alkaline batteries and easily fits inside your shirt pocket. Best of all, the MiniBump gas generator is extremely cost effective! The field replaceable electrochemical generating cell costs about as much as a disposable cylinder, but provides up to 1000 tests with no shelf life.
