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.
In various market segments – from the automotive industry to refrigeration and air conditioning technology to the manufacture of semiconductor components and solar technology – our leak detectors provide the highest quality and increased process safety.

The time and money required for maintenance and troubleshooting of your products will be reduced to a minimum and your ongoing operating costs will be significantly less.

Our leak detector, is so highly sensitive that a release of less than one millionth of a gram of gas can be shown to be a leak
