Technical Parameters

1. Four testing methods: Wire method, Point method, Area method, Custom method

2. Microscope resolution: 1μm

3. Microscope magnification: 10～300 times (adjustable according to user's research requirements)

4. Optical system: Original imported 3.0 camera, 8 million pixels

5. X, Y platform equipped with imported high-precision displacement grating scales, and magnetic levitation moving platform to ensure movement accuracy error <2μm, repeat positioning accuracy 1μm

6. Chord length test range: ≥1μm (user adjustable), chord length resolution: 0.1μm, identified bubbles provide multiple color options for users

7. X, Y moving platforms are directly driven by motors, without motor or screw transmission links, reducing mechanical transmission vibration and error, ensuring platform parallelism <1μm during operation

8. Testing time: ≥1 minute, varies depending on test conditions

9. Automatically generated reports include a detailed list of bubble chord lengths (areas), facilitating result review for research experiments

10. Specimen size: Maximum 200mm, compatible with irregular and circular specimens

11. After testing, the device software automatically completes image stitching and inserts the stitched image into the appropriate position on the report's front page, requiring no manual intervention

12. X, Y bidirectional displacement platform, net movement range ≥200mm

13. The device features "fuzzy origin" and "jog/continuous movement" functions, allowing users to start tests directly after startup or when changing specimens for multiple tests without repositioning the origin, reducing test time and improving efficiency

14. Measurement data deviation: Air content ≤0.3%, spacing factor ≤0.01

15. Software supports manual/automatic operation modes; automatic mode is one-click operation without manual intervention, manual mode allows users to measure chord length, area, perimeter, etc., of any bubble as needed

16. Measurement results display: Air content, average bubble chord length, number of bubbles, average bubble radius, average specific surface area of bubbles, and bubble spacing factor; all data generated as an Excel list

17. Automated measurement system for operation and analysis; users only need to place the sample on the test platform, and the system automatically completes the remaining tasks and generates reports

18. Data acquisition and control cables use DB interface mode, more stable, reliable, and convenient for plugging and unplugging

19. The product supports custom method user-defined file import, allowing testing of irregular specimens for convenient field testing

20. Equipped with high-configuration computer, precision grinding/polishing machine, and multi-grade diamond grinding/polishing discs
