The Importance of Bump Testing & Calibration

As the years have gone on, gas detection technology has developed rapidly, bringing with it the introduction of “maintenance free” gas detectors. As a result, gas detection users have become more reliant on the gas sensor lasting longer, assuming that the detector will work properly without routine calibration.

However, this isn’t the case – the only way to verify a detector is fully functioning and working to the best of its ability is through routine calibration and bump tests.

Although bump testing verifies the condition of the sensors and the alarms, it doesn’t determine the accuracy of the instruments readings if the detector fails its bump test then it the gas detector must be readjusted through a full calibration. Calibration involves two steps – first the instrument must be zeroed and then the span must be set. Calibrating an instrument is the process of determining the performance parameters of an instrument by comparing it with the measurement instrument.

There’s a lot of confusion surrounding calibration frequency – so how often should you be calibrating your gas detectors? Typical calibration frequencies for most gas detectors are between 3 and 6 months, but calibration frequency really depends on your usage – for example if you have a gas detector that you’re only using twice a year then it must be calibrated before each use.

A successful calibration service can significantly contribute to profitability by reducing costs and saving time. Inadequately calibrated gas detection equipment may give false readings which can affect processes, halt maintenance works or create doubt in the accuracy of deployed gas detection equipment.
