Helium Leak Testing

Helium Leak testing is performed to detect and locate leaks in

1. The pressure increase in a vacuum - reservoir
2. Pressure decrease in pressure - tank

This is inclusive of welded, brazed, adhesion-bonded and other assemblies.

The requirement of leak testing is quantized by the maximum allowable leak rate.

TCR Advanced

Helium Leak Testing

instrument has an approximate capacity of 10 m3/h (7 cfm) with usable helium sensitivity in the 10-11 atm.cc/s range. The unit has a dedicated sniffing unit, based on a well-proven leak testing concept, and is also available for outboard leak testing applications. The leak rate value is 1 mbar l/s if in a vacuum-reservoir with a volume of one liter, the pressure rises in one second about one mbar or in a pressure-reservoir it drops about one mbar in one second.
