Calibration Leaks for Helium Vacuum Leak Detectors UL1000/UL1000Fab/UL5000

Calibration test leaks with gas reservoir for vacuum applications


Various types with different leak rate ranges:

TL7 :          Capillary leak with helium gas reservoir and manual valve

                   Leak rate range 10 E-7 mbar l/s

                   Connecting flange DN10KF

TL8/9:        Permeation leak with helium gas reservoir and  manual valve

                   Special quartz bulb with a high helium permeation rate adjusts the constant

                   gas flow.

                   Leak rate range 10 E-8 mbar l/s or  10 E-9 mbar l/s

                   Connecting flange DN10KF


TL4-6:         Universal gas source for the fast insert in a variety of applications.

                   Helium capillary leak for vacuum  and sniffing applications.

                   Adjustable leak rate in the range between 10E-3 to 10E-5 mbar l /s .

                   Besides helium, which is included in delivery, the TL4-6 is also usable 

                   with different kind of gases.

                   Connecting flange DN 10 KF



  • Inured to pollution
  • Metal-free flow reduction for low temperature dependences
  • Detemination of the nominal leak rate by comparison with a calibrated leak having a PTB certificate
  • Inspection certificate ( included ) in accordance to DIN EN 10204:2004-3-3.1
  • DAKKS certificate(optional ) traceable to PTB

Typical Applications

  • Vacuum and Sniffing Leak Detection Applications
