Filter Testing Machine, Filter Paper Pore Size Tester
Filter Paper Pore Size Tester is used for the determination of the maximum pore size of the filter paper. Filter Paper Pore Size Tester is used to test aperture of oil filter material and pore size of air filter material element, filter cloth and filter paper. Applied to R &D of the new product and for Quality control department. Filter companies and users,testing center and Quality inspection and supervision institutions. Related standards: ISO 2942:2001 Hydraulic fluid power-Filter elements-Verification of fabrication integrity. GB/T14041.1-1993 National Standard Hydraulic fluid power-Filter elements-Verification of fabrication integrity. CFS/T 8002-2011 Industry standards Oil filter Material-Aperture test method.
II. Instrument features:
The equipment is small, light weight, easy to move, the use of advanced electronic technology, parameters can be pre-set, large LCD display pressure and automatically calculate and display the aperture value, every step of the user interface have text prompts, easy to operate. Printing out the average numerical aperture of each test piece and a group of test pieces, each test piece was not more than 10.

IV. Instrument characteristics:
The principle is based on the principle of capillary action, as long as the air is forced through the measured fluid is a measured wet materials of the pores, the liquid to be tested so that the air expelled from within the tube sheet maximum porosity, pore emerge when the first bubble required pressure, liquid surface tension, capillary equation can calculate the maximum pore size and average pore size of the test piece under the measure temperature using the known.
