Paper air permeability tester LD-TP-J10 (B) is designed to measure the air permeability using method of Gretel Tester which evaluates the breathability of paper, paperboard and wool fabrics. Air present in the inner cylinder is compressed, some air passes through the sample for certain time. Time is measured by manual stopwatch.
