BLD-TQ20

Paper Porosity Meter

In line with the GB458 standard, the addition of a dedicated probe can test the vapor transmission rate of cigarette disc paper, the sample size is 60 * 100 (mm), and the Measurement range is 0-1000ml/min.

Introduction

The paper air permeability meter is a special device used to measure the air permeability of paper or cardboard. It is used to evaluate the degree to which a paper material impedes the flow of gases, i.e., its air permeability. This instrument usually follows the international standard ISO 5636 or TAPPI T 460 to ensure the accuracy and comparability of test results.

The paper air permeability meter works by creating a gas pressure difference that moves gas through the paper or cardboard sample to be tested. The sample is sandwiched between two gas chambers, with a fixed gas flow rate in one chamber and a measured gas flow rate in the other chamber. By measuring the volume of gas passing through the sample per unit time, the air permeability of the paper can be calculated.

BLD-TQ20 This instrument complies with the GB458-89 national standard and is used to measure the air permeability of paper. Adding a special measuring head can also test .

Note: Keep the vacuum degree unchanged during the test (100 mm water column or 200 mm water column)
