PMI Liquid Liquid Aperture Analyzer LLP

characteristic

1. Can detect samples with nanoscale pore size

2. Testing for small apertures only requires a small sizeThe testing pressure（Approximately 1/3 to 1/5 of the pressure tested by gas-liquid method)

3. Suitable for testing samples of various shapes (such as sheet, rod, tube, hollow fiber...)

4. Multiple wetting and testing fluids can be selected (such as water, alcohol, Silwick, and Galwick)

5. Testing is conducted in quality control, research and development, or various user-defined modes

6. Real time testing graphic display

7. *Automation and Computer Control
