SEMA Gases is a company specialised in span gases in disposable cylinder cans established in The Netherlands. It all started from the desire to create a brand which is applicable for all brands of gas detection equipment.
SEMA Gases are used for calibration of portable gas detection instruments and calibration of fixed gas detection systems. They produce single gases (flammable gases, oxygen, toxic gases) and gas mixtures (2, 3, 4 or 5 gas mixtures) in various cylinder sizes 10 ltr, 34 ltr, 58 ltr or 110 ltr. Also available are the corresponding flow regulator valves with different flow rates and thread connections. Manual type flow regulators are used for diffusion-type gas detecting instruments which do not have a pump or with a hand pump. Demand flow regulating valves are used for gas detection instruments with an internal (or external) pump. SEMA Gases also supplies accessories like gas sampling bags, sampling hoses, calibration adapters and carrying cases.
SEMA Gases are being distributed across the globe by various specialised resellers. GMS Instruments is the official SEMA Gases distributor of the Benelux.
