Fuel cells are used in automobiles, spacecraft, remote weather stations and submarines. Other uses for hydrogen are in the fertiliser and paint industries, in laboratories, in the food industry and the chemical industry. Hydrogen is also used in welding processes. TIG welding and plasma welding are particularly noteworthy here.

Hydrogen is required as a reducing agent in chemical industries. Hydrogen has higher requirements for material stability than other gases. Our customers who use instruments in hydrogen applications are often in the automotive industry, the manufacturing of fuel stations, gas supply systems, test benches for laboratories, gas analysing equipment, etc.
