Product advantages
Reliability
- Complete testing methods: capable of automatic bubble point,enhanced bubble point, and diffusion Flow, pressure attenuation,and water intrusion testing.
- High testing accuracy and reproducibility: from small-scale filter membranes to large-scale filtration
- Comprehensive power on self-test function: can check the air source pressure, internal electronic proportional valve, internal valve,internal sensor, airtightness, and electrical circuit for normal operation
Usability
- Shorten testing time: Professional control circuit design and precise algorithm software reduce testing time by 20% to 30%.
- Software independent upgrade: Customers can upgrade on site independently, eliminating the hassle of returning to the factory for upgrade and downtime, and reducing downtime.
- The file has multiple retrieval functions; PDF files can be printed and exported.
- A 15.6-inch large flat true color touch screen with comfortable viewing angle and IP54 protection level.
Compliance
- Scientific and convenient data management: USB drives can easily import and export PDF versions of data between testers and computers.
- Fourth level user access permission management, making database usage and management more secure, organized, and in line with GMP production requirements.
- It has a second level electronic signature, which has handwriting function and fully complies with GMP requirements.It also meets the requirements of 2FR Part 11 for electronic data integrity, electronic signature, and audit tracking.
- Comprehensive data file management, including seven types of record files including “audit trail” and “instrument log”.
- Through CE certification, the product complies with EU regulations.
