Determine Your Leak Rate Now

Using an accurate leak rate is critical to the success of your leak test. Instead of applying guesswork to balance accuracy and cycle time, try our leak calculator. Just enter your known values below (Volume of Part and either the desired leak rate or test cycle time) and click “Run Leak Test”. The unknown attribute (Leak Rate or Time) will be generated for you.

You can also download our leak rate calculator app to do leak calculations on the go with your phone or tablet (scroll down for more information).
