WebHelium leak detectors are the ideal solution for leak detection and leak-tightness testing under vacuum. The test gas helium is safe and a small, light molecule which is suitable for detecting micro leaks. The detection range of helium in vacuum tests lies between 10 -2 and 10 -13 Pa · m 3 /s. WebLeak checkers that have their own turbo pump attach to your vacuum chamber and pump it down. Then you spray a very small flow rate (just barely coming out) of helium around your seals. If any helium makes it through, the pressure seen by the leak checker will go up, indicating you have a leak.
