RYOEX launches a limited-time "Up to \$12,500 Deposit Bonus Campaign" in June 2026.

Fukuda Co., Ltd., which develops, manufactures, and sells leak testing equipment to inspect airtightness and sealing performance, provides a technical document that clearly explains the methods and theories of airtight testing, titled "Technical Manual." We are offering it as a PDF file. Please take this opportunity to download and view it!

● What is a hydrogen leak detector? It can measure leaks in small areas that could not be detected in air leak tests and can also identify the leak locations. It is a detector that uses a mixture of 5% hydrogen and 95% nitrogen (non-flammable gas: ISO10156:2017) as the tracer gas. ● What is a helium leak test system? It is a leak test system suitable for high-precision or high-pressure leak inspections. The helium leak test system uses helium gas as the detection gas (tracer gas) and detects the helium that has leaked out. It is the leak test method among Fukuda's leak testers that can detect the smallest leaks.

● What is a flow meter? Flow meters measure flow rates using mass flow meters or laminar flow meters and perform pass/fail judgments based on flow rate criteria. They are ideal for measuring airflow and conducting performance tests. "FMZ-1063 series" This is a flow tester equipped with a mass flow meter. It offers high precision of ± 3.5 % of R.D. ± 1 digit (in the normal flow range). It features a time-saving function (scan measurement). The FMZ-1063 is a compact, all-in-one flow tester with various functions. "FU series" This is a flow measurement unit that integrates laminar and differential pressure sensors, making it smaller and lighter. When connected to a display indicator (model: MI-170), it can provide direct flow readings as well as pressure and flow judgments. "FLF-110 series" This is a laminar flow meter capable of measuring a wide range of flow rates from 2 NmL/min to 500 NL/min.

In civil engineering sites, there are many instances where sheet boards are used for temporary roads, access routes, heavy machinery work yards, and material storage areas. Traditionally, steel plates have been the mainstream choice, but due to their weight, they require considerable effort for transportation, installation, and removal, which can affect work efficiency depending on site conditions. Hyper CLT sheet boards are civil engineering materials made from CLT, which is wood. While being a sheet board that utilizes wood, it can serve as an alternative to steel plates for measures against muddy conditions, ground protection, and ensuring work pathways. The 5×10 board weighs approximately 230 kg, and the 5×20 board weighs about 460 kg, making them lightweight and easy to handle even with small machinery, contributing to reduced handling and construction burdens on site. Additionally, the unique properties of wood help in reducing glare, lowering noise, and fixing CO2, leading to environmentally friendly proposals. By leveraging the characteristics of wood instead of steel, it also aids in improving the working environment during summer and addressing noise issues in surrounding areas. As a registered technology with the Ministry of Land, Infrastructure, Transport and Tourism under NETIS "TH-250021-A," it is an easily applicable alternative material for public works that encourages creativity and safety measures. It is recommended for companies considering wood, sheet boards, timber, civil engineering applications, and civil engineering CLT. We also accept requests for materials tailored to site conditions and consultations for implementation. Proposals can be made for both public and private construction projects.
