So you think your gas detectors don't need to be bump-tested and that they are virtually maintenance free?

摘要

The fact is, calibration and bump testing your monitor is the only way of knowing if the monitor is working correctly. The following discusses why you should consider using gas mixtures of a known concentration to perform bump testing. You know an instrument is working correctly after a calibration. The real question is how confident are you that an instrument is working correctly in the period between calibrations? A calibration is the adjustment of an instrument to respond correctly to a known concentration of gas. A bump, or function, test is a verification that the instrument responds within acceptable limits to a known concentration of gas. The following is a discussion of why calibration and bump testing is so critical.
