3H-2000PB full-automatic bubble pressure method filter membrane pore size analyzer is a kind of instrument produced by BeishiDe Instrument Technology (Beijing) Co., Ltd and used to measure pore diameter, permeability, fluid flux and other related parameters of the materials with through hole by relying on liquid displacement technology (i.e. bubble pressure principle). This instrument uses infiltrate liquid and gas as the carrier, and is more pollution-free, safer and more convenient compared with mercury intrusion method. In addition, this method is also a standard method for ASTM thin film measurement.
Through hole test of filter membrane, fiber membranes, battery diaphragm, fabric, non-woven fabrics, paper, filter element, ceramics, cemented metals, rock, concrete and other materials.

Technical advantages and features:
Multiple sample-racket option
Can adaptive to sample pools with different sizes and different types, it can measure thin films with different diameters, no need to use multiple sample pools, i.e. single sample pool can be used to measure round film, as well as measure hollow fiber film.
【Patented Name】:Bubble pressure method pore size analyzer with sample pool which can adapt to different samples with multiple sizes.
Originally created air inlet system by Beishide: it adopts embedded air inlet system, the test gas will extend to the bottom of sample pool along with the air inlet pore passage on the side wall of the sample pool, then adding pressure to the sample film from the upper of the sample pool, the gas is flowing along with the side wall of sample pool so as to easy to mantle and dismantle it; it adopts built-in air inlet system, which avoid gas inlet from pool cover (sample pool structure with externally installed top inlet air pipe), and solve the problems of inconvenience in suing and poor gas tightness.
Vacuum Wetting-assisting Device
The Beishide originally created vacuum wetting-assisting device integrated with host is equipping with quick retractable structure, which can use vacuum wetting-assisting to materials that are difficult to be wetted, so as to realize fast, efficient wetting samples, and improve wetting efficiency and easy to operate.
【Patented Name】:Bubble pressure method pore size analyzer with vacuum wetting-assisting device
【Patent Number】: 201420148359.9
Dual measuring-range segment test
High precision originally imported dual-pressure sensor and dual-flow sensor, with segment pressure measuring range and segment flow measuring range, complementary measuring range, automatic shift and low measuring range sensor protection, so as to make test result more accurate, and we are the factory with highest test precision in the circle in domestic market presently.
