Bump / Calibration Gas Cylinders

Bump / Calibration Gas Cylinders

The difference between bump testing and calibrating is that a bump test is a brief exposure to gas, in order to verify that the sensors respond within a specific boundary and the detector’s alarms function properly. A bump test checks that the sensors respond to the target gas, it also verifies that the display reacts. It confirms that all the alarms are activated and the detector goes properly into alarm.

A calibration is a “resetting” of the detector’s response against a known concentration of target gas, in a balance of synthetic air or nitrogen. This will determine the relationship between the detector’s reading and the actual concentration of the component gas of interest. Adjustment involves modification of the detectors response to bring the reading into line with what is expected while exposing the instrument to the known source.

Please Note: we also supply a full range of regulators for use with the bump / calibration gas cylinders.
