Verification of tightness test devices

The calibration leaks lend themselves to the verification of tightness test devices, based either upon the deformation or the pressure difference principle. This way, the proper functioning of the device may be checked quickly and conveniently.
The capillaries, tailored to the desired leak rate, offer a precise airflow resistance. The air leaks into or out of the box through the capillaries.
The calibration leaks are robust and characterized by an easy usage and a long life expectancy. The calibration leaks should be stored in a dry and dust-free place. It is best for them to be kept in the included box.
Inappropriate storage or dirty compressed air may af-fect the leak rate of the calibration leaks. We recommend a yearly calibration.

The fabrication of the calibration leaks ensures a tolerance of ± 10% of the standard leak rate. The precision of a calibrated leak rate is ± 5 %, resp. + 5µg / min.The calibration takes place under controlled envi-ronmental conditions. Variations of these condi-tions affect the leak rate.

Standard and theoretical valuesThe standard leak rates are guiding values, occur-ring under the following environmental conditions
- Air pressure 960 mbar
- Temperature 20° C
- Air humidity 40 %
