The Leybold UL 100 Plus Helium Leak Detector is used for detecting leaks and for quantitative determinations of leak rates. The smallest detectable helium leak rate is 2*10-10 mbar ltr/sec.

The UL 100 Plus consists of the leak detection module and the pump module and is supplied ready for operation, with the leak detection module matched to the pump module and calibrated. The leak detection module may be used individually for detecting leaks in vacuum systems. In this case, make sure that the leak detection module is connected to a point in the system where the pressure will certainly always be less than 0.2 mbar.
