DHP 145 Test System

Test System DHP 145 for testing tightness and leackage for a high diversity of components and devices

With Leak Test Systems of series DHP 145 it is possible to test tightness against over and low-pressure of components of different dimensions and shapes. The leak rate is determined depending on pressure.

The test rig is working at test air temperatures from -40°C up to 120°C. A heat exchanger protects the measurement instrumentation against damages because of too low or high temperatures during low pressure operation. For external connection the test rig has a test air adapter, a pressure measurement port as well as a temperature sensor which have to be connected with the test sample. All connecting lines are 2 m long so that the sample can be in a climatic chamber during the test. The whole inscpection process is carried out primarily automatic and is controlled by means of the PC-based software DHPWin.
