Description

The MiniBump Test System is an ultra small, battery powered gas generator specifically designed for bump testing Chlorine, Hydrogen, Hydrogen cyanide and Hydrogen sulphide gas sensors. A small air pump draws in ambient air to blend with the electrochemically generated gas which permeates out of the cell and onto the gas detector sensor. Two AA alkaline batteries provide approximately 10 hours of operation and each gas source will provide up to 1000 bump tests (at approximately 30 to 120 seconds each).

The generating gas sources are interchangeable. The microprocessor reads the type of gas from a memory chip embedded in the cell body. It then self adjusts for each type of gas output. Bump tests provide an easy and quick way of checking the performance of gas detectors. Bump tests should be done monthly as needed or required by law. If the bump test fails, a full calibration should be done.
