A Helium Leak detector, also known as a Mass Spectrometer Leak Detector (MSLD), is used to locate and measure the size of leaks into or out of a system or containing device.   The tracer gas, helium, is introduced to a test part that is connected to the leak detector.  The helium leaking through the test part enters through the system and this partial pressure is measured and the results are displayed on a meter.

Ultrasonic Leak Testing Technology Ultrasonic Leak Testing

Ultrasonic leak detectors are very sensitive to sound. When properly calibrated, a high-quality ultrasonic leak detector will enable users to hear the blink of a human eye. This type of leak testing can be performed in an open or enclosed area and can be calibrated to isolate the sound produced by the leak. Ultrasonic leak detection focuses on a specific frequency band of sound; therefore, wind noise, voices, traffic, and most normal operational sounds can be filtered out and will not affect the accuracy of the test.
