Test leak

Reliable accessory for the ZED device family

The ZELTWANGER test leak is used to test and configure leak testing devices.

For this purpose, the test leak is connected to the device leak simulation. The test leak comprises a specially manufactured, temperature-resistant glass capillary, which is protected from contamination by a pre-filter and from damage by metal housing. It is manufactured to a specific test pressure and a specific leak rate.
