Gas & Calibration Solutions

APC Techsafe supplies a vast range of calibration and bump test gases. Bump testing is crucial for confirming the ongoing operation of your gas monitor. 

A bump test exposes the detector to a gas concentration that exceeds the alarm set-points to confirm the sensor’s ability to respond and verify that the audible and visual alarms are activated. 

Frequent bump testing is consistent with industry best practices and recommended to be performed each day before use. Linear drift, contamination, consumption of an electrochemical cell or simply a blocked filter may result in a failed bump test. If the readings fall outside of the specified value for a bump test then a recalibration is required.
