[Notice of Exhibition Participation by Fukuda Co., Ltd.] 2025 YOKOHAMA Automotive Technology Exhibition

Air leak tester specifically for airtightness inspection of large battery cases and similar items.

Fukuda Corporation will exhibit at the "2025 YOKOHAMA International Automobile Technology Exhibition"! Please be sure to check out this product at Fukuda's booth! This product is an air leak tester for battery cases of electric vehicles (EVs). The battery case features a structure that is "large with a significant internal volume, and deformation is expected due to internal pressurization." As a result, air leak testing generates noise caused by "the large size and volume" and "expansion or deformation due to internal pressurization." This product is characterized by the use of newly developed smoothing and linear fitting correction functions to reduce this noise during measurement. Additionally, to achieve precise low-pressure control and flow expansion for large volumes, we provide a bypass box (CBU-600) equipped with a pressure regulator that allows for accurate pressure control and a pressure valve with a large effective diameter to supply high flow rates.

Separate type air leak tester "LPU-300 series" "LPU-100/024 series"

The air pressure unit and measurement sensors can be bundled together, while control and display options are available separately. The "LPU-300 series" is the smallest measurement unit in Fukuda's history, making it ideal for direct attachment to as small a workpiece as possible. It can achieve higher measurement sensitivity compared to conventional all-in-one leak testers (depending on measurement conditions). The "LPU-100 / LPU-024 series" is used as a separate air leak tester in combination with display units (MI-170 / MIZ-0175 / DG-960). The separate display design makes it easier to position the measurement unit close to the workpiece. 【Features】 ■ Compact design that is easy to integrate into measurement devices ■ LPU-300 with control circuit sold separately, and LPU-100/024 where control is left to the customer ■ Rational and low-cost, choosing only the necessary functions ■ Even at a low cost, the differential pressure sensor is equivalent to general-purpose models ■ LPU-300 has a sensor volume of less than 1 mL, excelling in high-sensitivity measurements *For more details, please refer to the PDF document or feel free to contact us.

A masterless air leak tester that does not require an external reference during measurement. It measures the differential pressure between the workpiece and the built-in master tank.

This is a masterless air leak tester that does not require an external reference during measurement. It performs differential pressure measurements using an integrated master tank. Since there is no variation in the built-in master itself, stable measurements can always be achieved. Furthermore, this is our top-of-the-line model of the masterless leak tester, which also realizes a reduction in measurement time through mastering measurements. ● Equipped with preventive maintenance functions ● Mastering correction function ● Self-diagnosis function ● 5.7-inch touch panel display ● Network communication compatible (optional)

A versatile air leak tester that can flexibly adapt to various measurement environments. It is Fukuda's flagship model.

A versatile air leak tester that can flexibly accommodate various measurement methods (comparison between workpieces, comparison between workpieces and masters, comparison between workpieces and fixed masters (masterless)) and measurement environments. With a rich lineup of nine types that can handle high pressure, it allows for high-precision measurements in a short time through mastering measurement, making it Fukuda's flagship model. The masterless differential pressure air leak tester 'FLA-0200 series' is also available. ● Equipped with preventive maintenance functions ● Mastering correction function ● Self-diagnosis function ● 5.7-inch touch panel display ● Network communication compatible (optional) *Please contact us if you require a test pressure of 1 MPa or higher.

A high-sensitivity leak testing machine that uses hydrogen gas. It features improved convenience and operability, and is a compact detector equipped only with the necessary functions.

It is used to measure the overall leakage from the entire inspected item (work). - The work is covered with a chamber, tracer gas is filled inside the work, the leaked gas accumulates in the chamber, the leaked gas is stirred and forced to circulate, and the gas concentration is measured using a hydrogen detector [Atmospheric Pressure Chamber Method]. - After creating a vacuum in the chamber, atmospheric air is introduced into the chamber, and gas is directed to the hydrogen detector, allowing for highly sensitive measurements [Vacuum Chamber Method]. There are two methods. The design is compact and lightweight, making it easy to integrate into equipment. Additionally, the concentration resolution capability is ultra-sensitive up to 0.1 ppm (depending on the set conditions and environmental conditions). *For more details, please contact us.
