Leak calibrator

For reliable leak testing devices

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

For this purpose, the leak calibrator is connected to the device leak simulation and the required leak rate, depending on the test pressure, is set using a precision throttle.
