Helium Testing Equipment

What type of equipment does ATS use for helium testing?
ATS uses a portable leak detector that weighs only two pounds and can detect very small leaks in objects that have a slight helium/air pressure inside. It is sensitive to helium concentration as small as 2 ppm, which is equivalent to a leak rate of 5 x 10-6 atm-cc/sec.
