Paper Testing Equipment for Filter Paper Pore Size , Air Pressure 0 - 20kpa

Paper Testing Equipment for Filter Paper Pore Size , Air Pressure 0 - 20kp

Introduction

1.Electronic pore size tester is designed according to QC / T794-2007 standards. According to the principle of capillary action, as long as the measured air forced by a liquid wetting of the test material pores, the air out of the test piece of the largest pore tube of liquid, so that the corresponding hole when the first bubble required pressure. Using the known tension of the liquid surface at the measured temperature,

2.The maximum pore size and average pore size of the test piece can be calculated using the capillary equation.
