Test gases in larger sizes

Depending on the type of gas, our test gases for portable and fixed gas detectors are available in different cylinder sizes. The test gas cylinders are disposable containers made of aluminium or steel. A type 715 gas withdrawal fitting with a fixed flow rate of 0.5 l/min is used to withdraw gas. The carrying box can accommodate two gas cylinders and the withdrawal fitting.
