Leak detector

A nine-pound portable helium leak detector, the HeliTest(TM) provides rapid purging and setup ease that permits checking a 10,000-tube condenser in half the time of previous methods. It can pinpoint in one minute or less a remedying air in-leakage, a leaking valve or flange. Unit can detect leaks as small as 2 ppm and indicate them visually and with sound. A pump brings the gas to be tested to a small quartz membrane that is heated to a temperature that makes it permeable only to helium. Helium flowing through the membrane is pumped by a specially developed ion pump and detected by its current. The HeliTest`s maintenance is limited to battery charging.
