  • Any location or environment in which you need to calibrate a gas detector/sensor
  • and many more...

Key Features

  • Easy access and transport of the tools required for calibration
  • Fittings and adapters accommodate different sized gas cylinders
  • Industry standard calibration adapter plug fits all internal sensors
  • Weather resistant carrying case (complete Calibration Kit only)
  • Calibration gas cylinders are sold separately and cannot be shipped outside of Canada


The complete Calibration Kit comes in a durable, hard plastic carrying case and contains the items necessary for common field and shop calibration. If not all items are required, choose a smaller kit with the items you do need.

Cylinders of zero air or calibration span gas are not included; these must be ordered separately. CET offers a range of gas types and concentrations in 17 L, 58 L and 100 L sizes. However, gas cylinders cannot be shipped from Canada to other countries, including the USA. Contact CET or our Customer Support Team at for more information.

NOTE: These calibration items are not suitable for use with the YES AIR or YES Plus LGA.
