ABSTRACT:
A leak test arrangement having a leak calibration device is disclosed. The calibration device is connected into communication with the leak test arrangement and provides a controlled source (sink) of fluid at a predetermined amount. The calibration includes a substantially sealed volume of fluid in fluid communication with the test arrangement and a control arrangement for heating and/or cooling the volume to produce the source (sink) of the calibrator.
