Test gases

Test gases for portable and fixed gas detectors are available in cylinders of different sizes, depending on the type of gas. We offer cylinders with gas capacities of 12l, 34l, 58l and 110l. All containers are disposable and made of aluminum or steel.

We also offer gas sampling accessories - such as regulators with a constant flow rate of 0.5l/min, or transport boxes for safely carrying up to two gas cylinders and their respective accessories.

Please find below an overview of the most common test gases offered by GfG as well as the accessories that are necessary for calibrating gas detection equipment.

If you have questions or the test gas you are looking for is not listed, please feel free to contact us.
