● 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.

We are pleased to announce that our employees have newly passed various levels of the "Machine Inspection" certification in the second half of the 2023 fiscal year. ■ Breakdown of Successful Candidates Special Level of Machine Inspection: 1 person Third Level of Machine Inspection: 3 people The special level requires more than five years of practical experience after passing the first level. The pass rate is very low, and it demands advanced and extensive specialized knowledge. Our company has many other certified professionals as well. You can view them through the link below. We will continue to strive for further technical improvement, strengthen our quality assurance system, and assist everyone in the manufacturing industry.
