Based on liquid-liquid displacement theory, the PSMA porometers measures pore size of 8－500 nm. Apart from ultra-filtration membranes, the pinhole defects in nano-filtration, reverse osmosis and the molecular-sieve membranes can be also analyzed. 

　　External Size: 500(L)×480(W)×230(H) mm

　　Working Medium: Water, Organic Solvents

　　Pore Size Test Range: 8nm－200nm

　　Test Object: Flat membrane, Tubular Membrane, Hollow Fiber Membrane

Instrument Functions:

　　1. Bubble Point Pressure Test

　　2. Maximum Pore Size, Average Pore Size, Most Probable Pore Size Test

　　3. Pore Size Distribution Test

Instrument Features:

      1. Nanopores can be measured without high pressure. Pore sizes down to 8nm can be accurately measured within 600 KPa pressure, whereas traditional gas bubble pressure instruments require 6 MPa pressure to achieve this. This effectively avoids the problems of compression and deformation of the sample caused by high-pressure testing.

      2. Chinese and English interface, fully automatic computer control and analysis system.

      3. Complete Data Processing Software.
