● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm. Please feel free to contact us for more information!

We are offering it as a PDF file. Please take this opportunity to download and view it!

What is an Air Leak Tester? An "Air Leak Tester" is a device that pressurizes the inside (or outside) of a sealed workpiece with air and determines the presence of leaks based on pressure changes. When a master with no leaks and a workpiece with leaks are pressurized, the pressure on the workpiece side decreases, creating a pressure difference between the two. By measuring this pressure difference, the presence of leaks can be determined. Generally, differential pressure air leak testing is widely used, but Fukuda also offers products that utilize direct pressure leak testing and flow meters according to the leak rate, in addition to differential pressure leak testers. Since the air leak tester uses air as the measurement medium, it incurs no running costs and is environmentally friendly.
