Product Information:
Test System for testing tightness and leackage for a high diversity of components and devices. With Leak Test Systems of series 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.

Test Procedures
Connect the test sample to the test air adapter, pressure port, and temperature sensor.
Place the test sample in ambient conditions or inside a climatic chamber if required.
Select overpressure or low-pressure test mode according to the test requirement.
Apply compressed air or vacuum to establish a stable pressure condition inside the sample.
Measure pressure, volume flow, and gas temperature continuously during the test.
Calculate the leak rate automatically based on flow behavior and pressure differences.
Record and evaluate the test results using the computer-controlled system.
Maintenance Information
Regularly inspect laminar flow elements to ensure accurate flow measurement.
Keep compressed air clean and dry to prevent contamination of measurement components.
Verify pressure and temperature sensors periodically for calibration accuracy.
Check seals, hoses, and connectors for wear or leakage before each test series.
Ensure proper functioning of the heat exchanger when operating at extreme temperatures.
