Onsite Helium Leak Testing Services

Helium Leak Testing is a specialized job. Finding a very small leak could be extremely tricky. Usually, the need for Helium Leak Testing arises when the vacuum pumping system is not able to achieve the desired vacuum or in cyclic processes the cycle time is increased due to leakages. Sometimes the leakage also affects the quality of the product being manufactured. Hence it needs expertise and a good understanding of Helium Leak Testing concepts along with practical knowledge of various applications.

1. Onsite Helium Leak Testing Services

We have been providing helium leak testing services to large number of Customers for varied applications and products like:

2. Helium leak Testing for “Type Testing” of products

Tekman offers support to its customers by helping them to choose the right Helium Leak Testing method, developing testing fixtures, defining test procedures, and handling technical data such as leak rate conversions.
