[Instrument Features]:

1. Full-range calibration against a standard flow meter, with a built-in data correction program for rapid instrument calibration. Utilizes a flow calculation method featuring high-precision sensors for dynamic measurement and a 32-bit high-speed ARM processor for automatic data processing and conversion.
2. Pneumatic automatic sample clamping and nozzle changing for rapid, accurate testing.

3.Microcomputer-controlled processing; test results are displayed directly, eliminating the need for manual look-up tables or calculations.

4. Touchscreen menu interface supporting both Chinese and English; equipped with a PC interface.
5. Ultra-quiet sound insulation and noise-dampening system.
6. Dual testing modes: constant pressure and constant flow.

7.Automatic nozzle cleaning system to eliminate errors caused by dust accumulation.

8.Airtightness testing mechanism for periodic checks of the instrument’s seal integrity.

9. Supports data storage and report printing, either locally on the instrument or via a connected PC.

10.Test data can be copied directly from the instrument to a USB flash drive, facilitating testing across diverse site environments. 11. Built-in thermal printer;

12. Optional barcode scanner and standard network communication module;

13.Optional standard API interface, supporting real-time data transmission with LIMS, automated workflows, and cross-system integration.
