With the development of the industrial manufacturing industry, consumers have higher and higher requirements for product quality, especially the waterproof sealing quality of products.Traditional water detection methods have low efficiency, high energy consumption and are greatly affected by human factors. They are gradually unable to meet the fast-paced detection needs of current factories.
Hirays, which is highly sensitive to market demand, has relied on 17 years of accumulation in the leak detection industry and combined with more than 5,000 actual customer service cases to launch high-precision leak detection equipment - HQ series hydrogen and nitrogen leak detectors, providing more efficient detection equipment for the manufacturing industry.
Hirays HQ series hydrogen and nitrogen leak detector
Hirays HQ series hydrogen and nitrogen leak detectorThe highest detection accuracy is5×10-7mbar·L/s, our company specializes inHigh-precision testing needsIndustry (e.g.:Automobiles, 3C, refrigeration, valves, die castings, etc.)It is built to meet the ever-increasing demands for high-precision and leakage detection.

It has the advantages of high sensitivity, single-station integration, high efficiency and economy.It also has four functions in one (hydrogen and nitrogen leak detection + air sealing + hydrogen and nitrogen gas filling + exhaust gas emission), which reduces equipment space requirements, is simple and easy to use, facilitates the equipment to be integrated into the production line faster, and improves the accuracy and efficiency of mass inspection of the production line.。

What is Hydrogen Nitrogen Leak Detection?Law?
Hydrogen nitrogen leak detectionLawAdvantages
Compared with traditional water detection and other airtight leak detection methods, the hydrogen-nitrogen leak detection method has more significant advantages:
High sensitivity: Can detect extremely small leak points, the minimum leak rate can reach 5×10-7mbar·L/s。
Easy to operate: Just inject the hydrogen-nitrogen mixed gas into the product to be tested/customized cavity, and use the HQ series leak detector to quickly locate the leak point.
low cost: Hydrogen-nitrogen mixed gas is low in price, which greatly reduces the detection cost compared to the same high-precision helium detection.
