Currently, many refrigeration equipment manufacturers face the following serious challenges:  Leakage risk: Insufficient accuracy directly challenges the environmental protection red line.Missing the detection of micro-leakage will lead to long-term risks of product performance degradation, compliance risks and brand reputation.  Low efficiency: The detection speed is slow and cannot match the rhythm of high-speed production lines, forming a production bottleneck.  Misjudgments occur frequently: human operating errors or poor equipment stability lead to missed detections and misjudgments.  Missing data: The lack of reliable data recording and traceability capabilities is not conducive to quality system optimization. How to achieve fast, accurate and reliable sealing testing has become the key to industry upgrading.

2 HM-500: Creating Lean Solutions for the Refrigeration Industry

In the face of industry pain points, for the detection of finished refrigeration equipment (filled with refrigerant), Hirays has launched the HM-500 multi-gas leak detector with its core quadrupole mass spectrometry leak detection technology and excellent R&D strength, providing customers with a more economical, efficient and comprehensive solution. This product has extremely high sensitivity, stable and reliable performance, and does not require tracer gas. It can directly detect a variety of refrigerants such as R134a, R600a, etc., and supports the flexible setting of multiple substances to be tested to meet the leak detection needs of different refrigerants.01 Extremely accurate, ending misjudgments  Ultra-high sensitivity: The minimum detectable leak rate is as low as 0.05g/a. It has extremely high sensitivity to common refrigerants such as R134a and R600a, and can quickly find small leaks.Its detection limit far exceeds industry standards, providing a reliable guarantee for meeting increasingly stringent environmental regulations around the world.  High flexibility: It can detect a variety of different gases at the same time and adapt to strict and complex process requirements.In addition, by setting the substances to be inspected, not only can the refrigerant inspection be completed efficiently, but also the inspection needs of different refrigerants can be met!  Wide range detection: It can detect the mass range of 2-100amu, and can detect most volatile substances that need attention in industrial environments.  Excellent stability: The RSD (relative standard deviation) of an international first-line brand for 100 consecutive tests is as low as 4.5%, while the RSD (relative standard deviation) of Hirays is as low as 3.8%. It has better stability and can effectively ensure the high consistency and reliability of the results in batch testing, achieving "no missed judgments and no misjudgments."

02 Extremely fast and efficient, matching the production line  Quick response: Equipped with a 3-meter suction gun, the response time is <1 second, which perfectly fits the rhythm of high-speed production lines.  Fast startup: startup preparation time is less than 5 minutes, reducing equipment standby time and improving production efficiency.  Data analysis: Built-in data recording function automatically saves complete detection data and forms an analysis report, providing a reliable basis for process optimization and quality traceability.

03 Minimalist operation, convenient and durable  Guided operation: The intelligent interface displays the status and leakage rate in real time, and is paired with a keyboard and touch screen to guide the operator to complete the measurement correctly.  One-click test of the sniffer gun: key instructions can be completed on the sniffer gun, without the need to go back and forth to the host, and the operation is smooth and convenient.When a leak exceeds the preset failure rate, the sniffer gun will sound an alarm to avoid inadvertent missed readings.  Ultimate durability: Ultra-long maintenance cycle (>1 year) can fully ensure the continuous and stable operation of the production line, and all components have excellent performance, long service life and durability.

Conclusion

As the manufacturing industry moves towards "lean" and "intelligent" today, every aspect of quality control is crucial. With its excellent performance, the Hirays HM-500 multi-gas leak detector provides a one-stop seal detection solution for home appliance manufacturing, auto parts, refrigeration equipment integrators and repairers, and even high-end intelligent manufacturing companies, effectively helping manufacturers improve product quality, reduce overall costs, and strengthen brand competitiveness.
