• Lowest detectable leak rate for helium < 5 x 10-12 mbar l /s.

• Faster detection times through an averaging method which adapts itself dynamically to the leak rates.

• Leak detection starting at an inlet pressure of 15 mbar.

• Short recovery time after helium contamination (≤ 5 min.).

• The leak detector may be moved to a different location immediately (≤ 30 s) after switching off.

• 3 freely selectable trigger thresholds

• Ion sources are backed with a 3-year guarantee for free replacement.

The Leybold Vacuum PhoeniXL300 is a direct replacement for the Leybold Inficon series of helium leak detectors known as the UL 100 Helium Leak Detector, UL 100 Plus Helium Leak Detector and UL 200 Helium Leak Detector. The Leybold PhoeniXL300 is also a replacement for the Leybold L200 Helium Leak Detector and the Inficon UL200.

It is comparable to other brands such as the Varian 979, Alcatel 142, and Veeco MS 40. The Leybold PhoeniXL300 is available with oil sealed or oil free backing pumps.

Other available helium leak detectors include the Alcatel ASM 120H, the Alcatel ASM182TD and the Alcatel 180T.
