Gas detection systems must be correctly specified, installed and maintained in order to be effective.
Anyone undertaking elements of this work should have access to the necessary equipment and be able
to demonstrate competence. This will usually mean having passed a training competency course.
International Gas Detectors run training courses for safety survey, specification , installation and
service aspects of hazardous gas detection systems. In addition IGD can supply test equipment and
calibration gases necessary to undertake this work.
Please the following points
1. A zero grade gas usually instrument air or Nitrogen and a suitable calibration gas mixture is required.
2. The correct gas adaptors must be used to apply gases to detectors when zeroing and calibrating.
Incorrect application of gases can affect calibration results
3. Use equipment and gases traceable to a national standard. Any calibration will only be as good as
the equipment and materials used.
4. IGD supply fixed flow regulators for use with IGD calibration gas bottles which supplies gas at
0.5l/min
