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.
