Fundamentals of Leak Detection

Unwanted leaks in any system can easily damage expensive equipment and machinery reducing the effectiveness of the process. The primary reasons for helium leak testing are quality, reliability, personnel protection, and protecting the environment. 

Unforeseen issues like vacuum leaks can become catastrophic for vacuum operations, operators, and the environment. It is therefore crucial to develop a mitigation plan ahead of these events so vacuum levels can be restored as quickly as possible. Whilst vacuum systems don't need to be vacuum-tight to run safely and efficiently, they do need to maintain proper operating pressure, gas balance, and an ability to reach and maintain ultimate pressure.
