The HC series adopts the mature pressure drop method detection principle, with a detection accuracy of 10⁻⁴ mbar·L/s.More than 20,000 units of this series have been deployed in customer production lines. They have been fully verified by the market and can meet the sealing detection needs of most industrial scenarios.

Hirays HC classic series provides a complete tooling adaptation solution, including test chambers of various specifications and customized tooling fixtures.Through the quick change interface, the change time can be controlled within 5 minutes.The test pressure is continuously adjustable within the range of 0~2.5MPa, which can quickly adapt to the testing requirements of different products.

Hirays HC classic series has a built-in data storage function, which can record 100,000 test results and supports exporting reports in Excel format through the USB interface.Equipped with a 7-inch touch screen that can display detection curves in real time, and an optional Ethernet interface to facilitate data upload and management.

Hirays HC classic series recommends standard calibration every 12 months, while performing equipment self-inspection procedures every month, and using standard leaks for accuracy verification every quarter.Regularly check the air source purification system and avoid using it in environments with strong vibration and strong electromagnetic interference. These measures can effectively ensure the long-term detection accuracy of the equipment.
