Ultra Sensitive Atmospheric Sampling (USAS)

The Next Generation in leak detection technology

Ultra Sensitive Atmospheric Sampling Leak-test Systems offer greater sensitivity, lower operating costs and smaller footprints than the best existing helium leak-test systems—all without vacuum.

• 1/3 the cost of helium leak-test systems

• 10,000 times more sensitive than helium mass spectrometer leak detectors—tests to 10 parts per trillion SF₆

• Leak tests to helium hard vacuum rate specifications without vacuum

• No need for costly vacuum components such as pumps, chambers, manifolding and valving

• Easier to use and maintain than helium leak-test systems: no mass spectrometer to maintain

• Efficient gas recovery system permits testing of approximately 15,000 standard components with only one pound of SF6 gas, therefore tracer gas costs are typically half that of helium
