It has an audit trail, USB data export and other functions, adopts a 10-inch true color touch screen design, a friendly man-machine interface, and simple, fast, and reliable operation.

1. Adopt an optimized Linux system;
2. Optimized test operation and shortened test time;
3. To meet offline online testing, using pressure sensors with higher accuracy and lower deviation bands to improve the test accuracy of the instrument;
4. Automatic self-test function: self-test of multiple performance functions of the instrument itself, after turning on the device has instrument self-test function, report faults in time.
5. Scientific user management, password login, user classification, electronic signature, etc., support multi-level user access permission settings, ensure data integrity, have comprehensive audit trail functions, and support manual or electronic signature;
6. The instrument comes with an audit trail function, and truly meets the requirements of data integrity;
7. Can establish 1000 sets of pre-stored programs, which can fully meet multiple filter types and different test conditions in the field, and the instrument is more simple and intelligent;
8. Increased the display curve of diffusion flow pressure, realized the display and printing function of three curves, optimized the air intake control unit, and greatly increased the air intake speed and stability;
9. Support USB disk data export function, which can not only export the original test data but also the source data and configuration data, so that the data integrity requirements are perfectly reflected in the instrument; if single data can export PDF style directly;
10. Can expand data communication and network interface requirements according to customer requirements, and support wireless communication functions;
11. Optimize the structure of the instrument so that its dust-proof and splash-proof level reaches IP54, and use quick connectors (Staubli connectors can be used) to avoid incorrect connection of the inlet and outlet pipes.
12. Test records and audit trails of the instrument both can be queried and exported;
13. High-precision sensors and optimized algorithms can extend the gas path to 100m, make the upstream volume test more accurate, and the instrument can better meet the conditions of field use without affecting the test results;
14. The built-in thermal printer avoids the risk of particle and ink contamination; External interfaces can be customized according to customer requirements;
15. 1000 user accounts, four levels of user management, and each user’s authority can be determined by default or customized methods;
16. Can test most up to 12-core 20-inch filter cartridges, which greatly improves the user’s work efficiency;
17. Rich data interface, the instrument not only includes standard digital and analog interfaces (RS232 / USB), but also can customize a variety of industrial buses and analog control ports according to customer’s needs.
