The air leak tester has become a measuring device! Overall accuracy has improved by 30% (compared to our previous model).

The "FLZ-0620 series" is an air leak tester with an automatic calibration function that maintains high precision and reproducibility by auto-calibrating the leakage amount during measurement. By achieving high stabilization of the reference tank (master), it suppresses zero drift of the master (reference). It features a separate structure that allows the workpiece and measurement unit to be placed in the same temperature environment, which helps to minimize flow changes due to temperature. 【Features】 ■ Tester is separated into a display unit and a measurement unit ■ Measurement unit and workpiece can be installed in close proximity, creating the same environment ■ Reduction of piping compared to conventional models is possible ■ Equipped with an auto-calibration function ■ Easy data input and output via USB host and USB function *For more details, please refer to the PDF document or feel free to contact us.

Please take a look at Fukuda's air leak tester!

  • Product news

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.
