How often do I need to calibrate my instrument?

In simple terms, the usual recommendation is that gas detection instruments are serviced and calibrated at least once a year, depending on the technology and the manufacturer. However, it is less well known that ATEX, IEC and British HSE standards all call for the bump test and calibration of any portable instrument used for worker health and safety protection in a potentially hazardous environment. That means before every use. 

Shawcity offers a full range of bump test and calibration gas for testing portable and fixed gas detectors.

Available in 34, 57 and 103 litre cylinders, we stock a wide variety of ready to use gases, with accessories and adaptors to help make bump testing your instrument as straight forward as possible. We also stock mixed calibration gases for instruments that require bump testing with more than one gas.

Our trusted calibration gas supplier Calgaz have recently published useful help and advice for anyone who uses calibration or bump test gas:
