1. High precision and stability: Unique channel design greatly improves circulation and ensures leak rate detection error within ±5%;
2. High tolerance: specially designed for earthquake resistance and fall resistance to improve product reliability and service life;
3. Wider pressure range: no chamber source pressure can reach 2MPa, meeting high pressure requirements;
4. High cost performance: extremely competitive price; unique design, low maintenance requirements.
itCompensates for air tightness detector calibrationmustUse other devices, the shortcomings of a narrow leakage rate range, to achieve the goal of manufacturers to efficiently calibrate the leakage rate of air tightness detectors.
Calibrate industrial measuring instruments, such as for calibrating the accuracy and reliability of flow meters, pressure gauges, thermometers, air tightness detectors, flow testers and other measuring tools; or it can be used for equipment inspection and accuracy confirmation.

In addition, it can also inspect and control the quality of production products, such as testing the air tightness of battery packs and fuel cells in the new energy industry; testing the sealing of mobile phones, smart wearable devices, and health monitoring equipment in the 3C industry; industries such as outdoor security, wire connection, home appliances, and medical equipment can also use LP airtight standard leaks to test the sealing and safety of their products.


Analysis of Hiraysi’s advantages:
1. Save costs and provide "instrument-jigs-accessories-testing platform" fully supporting leak detection equipment procurement;
2. Nanny-style service, from early research and development, delivery to after-sales, full-process service docking;
Harisi knows that only continuous innovation can maintain its leading position in the leak detection industry.Therefore, Hirays will continue to pay close attention to industry development and changes in market demand, rely on accumulated industry experience and rich customer cases, continue to strengthen its core independent research and development capabilities, and provide customers with high-quality, cost-effective "instruments-jigs-accessories-testing platforms" fully supporting leak detection equipment and one-stop services.
