type N1400, which is often used in generating stations.

Highlights in this range of gas sampling pumps are the special versions with heated pump heads --in this way condensation of the gas sample can be avoided. For aggressive gases there are ceramic and PTFE pumps in the range, and for particularly toxic, valuable, or even radioactive media, models with safety diaphragms can be produced. These gas sampling pumps can perform at flow rates up to 300 1/min, down to 0.5 mbar vacuum and up to 7 bar" pressure.
