Air resistance is the reisitance to the passage of air, offered by the paper structure, when a pressure difference exists across the boundaries of the specimen. It is quantified by obtaining the time for a given volume of air to flow through a specimen of given dimensions under a specified pressure pressure difference, temperature and relative humidity.
Labthink air resistance tester of paper is designed according to TAPPI T460 standard air reisistance of paper (gurley method).
Features of Labthink air reisistance tester of paper TQD-G1:
-- High precision sensors of electronic airflow and air pressure to ensure the accuracy of test data
-- 2 test modes are available for customers: fix pressure difference to test flux and fix flux to test pressure difference
-- Controlled by micro-computer, with LCD menu interface and PVC operation panel
-- Micro-printer and RS232
