フクダ List of Products and Services

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.

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)

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.

The "FL-612 series" is a product developed to enable effective temperature compensation for powertrains such as engines and transmissions. It features a correction function and correction mechanism that reduce misjudgments during airtightness testing in heat dissipation conditions occurring after cleaning, drying, and assembly processes. 【Features】 ■ Improved productivity (better straightness rate, avoidance of misjudgments) ■ Reduced equipment costs (elimination of cooling processes) ■ High-temperature work compatibility (supports after work cleaning and drying) ■ Improved accuracy (responds to changes in work temperature and ambient temperature) ■ Equipped with USB port *For more details, please refer to the PDF document or feel free to contact us.

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.

The functionality follows the FL-611, which boasts the highest installation record among our company's leak testers. 【Features】 ■ All stainless steel, non-copper specifications ■ Fluororesin is used for the resin piping ■ Designed for safety using the well-regarded FL-611 housing, known for its operability and visibility ■ The functionality similarly follows the FL-611, demonstrating high performance * For more details, please refer to the PDF document or feel free to contact us.

The "FLZ-0220 series" adopts high-performance correction functions (linear fitting), making it possible to suppress misjudgments caused by measurement environments (depending on environmental conditions). The touch panel has approximately twice the display area compared to conventional models, improving visibility, and the dedicated icons greatly enhance operability. We have prepared replacement jigs for our leak testers. *We also accept replacements from other manufacturers. 【Features】 ■ Touch panel adoption allows for efficient settings and functions ■ All necessary functions for air leak testing are included ■ Comprehensive self-diagnosis and maintenance functions ■ Easy operation with clear dedicated icons *For more details, please refer to the PDF materials or feel free to contact us.

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.

In the automotive industry, the airtightness of various components such as engines and fuel cell parts affects product quality. Particularly for parts used in harsh environments, even minor leaks can lead to performance degradation or failure.
