GassMann AS is your one-stop-shop solution for all of your calibration gas requirements. No more dealing with multiple local suppliers: slash your administration and delivery costs by using one supplier with global deliveries.


We promise you three simple - but essential, game-changing - things:

  • We'll get your calibration gas to you, wherever you are in the world. Our global hubs mean we can deliver with ease!
  • If your vessel ever misses a delivery through no fault of its own, we'll re-deliver to the next stop, free of charge.
  • Your gas detection calibration equipment is guaranteed to work with GassMann cylinders - we'll supply all the parts you need.

Our Non Reactive Mixtures have a market-leading 5 years shelf life, Quad Gas Mixtures 24 month shelf life and H2S/SO2 24 month shelf life. That means you can order in bulk up to two years ahead of your calibration gas needs - taking advantage of unique bulk discounts AND saving thousands of dollars by having just one delivery.


If that's not enough, we can also arrange bespoke gas mixtures - so if you can't find what you're looking for, get in touch to let us know!
GassMann precision calibration gas comes in three cylinder sizes 34L, 60L and 112L
