Helium Leak Detector – The clever and modular Solution. Simple Operation. Top Performance.

Leak Detection Methods

When searching for leaks with the SmartTest the test gas entering or escaping
through leaks in the sample is detected.
For gas to flow through a leak a pressure difference between the inside and outside
of the sample is necessary. For this either excess pressure or vacuum pressure is
generated inside the sample.

Vacuum method

In the vacuum method test gas is blown against the wall of the evacuated sample
from the atmosphere side. It enters the sample at leaks and is fed to the leak
detector.
The sample must be vacuum pressure-proof.
The sensitivity stages
counterflow ⇒ Twin-Flow™ low ⇒ Twin-Flow™ high
are run through.
The detection limit is lower than in the sniffing method. The helium concentration
at the leak must be known in order to quantify the leak. The state of equilibrium
must be waited for.

Sniffing method

In the sniffing method the test gas escaping from leaks in the sample into the
atmosphere is detected.
The sample must withstand the applied test pressure.
In operation with the sniffing probe a constant gas flow is sucked in from the
atmosphere. The helium proportion of the air (5.2 ppm) causes a leak rate display
of approx. 1×10-6 mbar l/s which can be eliminated by the ZERO function.
To detect a leak, the sniffing probe is applied to the points of the sample under
helium overpressure which are suspected of leaking. An increased leak rate value
indicates an increased concentration of helium and therefore a leak. The higher the
pressure and the helium concentration in the sample, the smaller the leaks which
can be detected.
The sensitivity stages
counterflow ⇒ Twin-Flow™ low
are run through.
The detection sensitivity and the quantifiability of the leak rate are less favourable
than in the vacuum pressure leak detection.

With its modular design and it's new wireless remote control RC 500 WL, the SmartTest offers the perfect solution for vacuum leak detection. Fast, reliable results, lowest detectable leak rates and short recovery time are what characterize the SmartTest and make it such a powerful and dependable product.

Utmost sensitivity in identifying even the smallest leaks. Quantification of the leaks. Outstanding reproducibility of the measurement. Helium test gas is non-toxic and non-flammable. Short measurement times
