Specifications don’t mean anything unless you understand how they impact your manufacturing process, which is why we have provided the following table!

Dimensions6 x 7 x 9 in. (15.17.78 x 22.86 cm)A very small footprint enables you to maximize your lab or automation space.

Pressure: 0.00001 PSI

Mass Flow: 0.01 SCCM*

High sensitive ensures your parts are within your manufacturing specification.
Internal Volume0.8 cm3A small internal volume is often overlooked when purchasing a leak tester, but it is one of the most important specifications. A small internal volume minimizes testing variability such as thermal drift.
