Gas dosing with ultraviolet lamps

The precise measurement of "nothing" since 1970

It is with our passion for precision that we support our customers with their vacuum applications. Vacuum allows a great variety of manufacturing processes. The same large field of applications is served by our vacuum products. Included applications are for example process industry, coating, analytics and R & D as well as semiconductor and solar.


  • Wide measuring range due to combination sensor piezo / Pirani
  • High accuracy and optimal resolution over the whole measuring range
  • Excellent reproducibility and long term stability
  • Short response time

Gas dosing with ultraviolet lamps

Ultralight is a company based in the principality Liechtenstein draws on its walth of experience in the field of development and production of ultraviolet lamps and components.


The lamps are used in industrial applications of curing special UV reactive lacquers, glues and inks. The lamps emit according to the lacquers´ requirements in the UV-A by 400 nm to UV-C by 250 nm. Different noble gases are necessary for the production of the UV lamps.


The quantity of noble gases when filled is dosed during the manufacturing process under vacuum with the help of a piezo and Pirani combination gauge VSR53DL. Quantity and type of gas depend on the type of lamp and ranges between some 10 to 100 mbar absolute.
