Calibration Gas

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.

Gases include:

  • ● 3 Mix + LEL
  • ● 4 Mix
  • ● Butadiene
  • ● Carbon Dioxide
  • ● Helium
  • ● Hydrogen Chloride
  • ● Hydrogen Cyanide
  • ● Isobutylene
  • ● Methane
  • ● Nitric Oxide
  • ● Nitrogen
  • ● Oxygen
  • ● Propane
  • ● Sulphur Dioxide

Please note that there can be a 2-3 week lead time to supply gases, ensuring you receive the highest quality of calibration gas with the longest expectancy.

For more information call 01367 899553 or email info@shawcity.co.uk.

Servicing

Alongside daily or frequent bump testing and calibration most manufacturers recommend an annual service for gas detection instruments. Shawcity’s manufacturer-trained and approved service engineers offer an in-house Service Centre for portable instruments and a field team for fixed systems, so you can be confident your equipment is maintained by trusted professionals and always performing at its best.
