Leaks for Helium Vacuum Leak Detectors

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

TL3-5/ 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

Advantages

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
