Presentation model of helium mass spectrometer leak detector made by staff at 20th Century Electronics. This was developed for internal use in the 20th Century Electronics factory by John Bargery, and won a Duke of Edinburgh Design Award in June 1976 that greatly aided commerical sales. The device under test for leaks was pressurised with helium and then checked with a probe sensitive to helium. The leak detector could be tuned to sound an alarm if it sniffed any leaking gas.
