Automatic Air Permeability Tester Schober Gurley Method ISO5636-1701507945154497

Working principle

Adopting tpressure difference method, the pre processed sample is placed between the upper and lower measurement surfaces to form a constant pressure difference on both sides of the sample. Under the action of pressure difference, gas flows from the high-pressure side through the sample to the low-pressure side. Based on the area, pressure difference, and flow rate passing through the sample, the permeability of the sample is calculated.

Features

The chips and sensors of this instrument are imported from the United States, with accurate test results, good repeatability, and high accuracy. The calibration of pressure sensors and flow sensors is traceable.

Exquisite design: The instrument adopts microcomputer technology, and the testing process is fully automated, fast, and accurate. Touch screen LCD display results, with data recording and processing functions, with printing output.

◆ Superior performance: Compared with traditional air permeability meters, this instrument has high advantages. It can set a higher pressure difference for papers with lower air permeability, and a lower pressure difference for papers with higher air permeability, making it easy to accurately measure results.

◆ Easy to use and high automation: Traditional permeability testers are not only slow and labor-intensive when testing, but on the contrary, the testing of this permeability tester is automatic and fast, and the accuracy of the test results is also guaranteed. Misoperation or low reproducibility of test results, which are caused by poor instrument design and manufacturing technology, have been effectively avoided in this instrument.
