Air Permeance Tester For Paper Schober Gurley Method Testing Instrument Fot Paper Packaging

Introduction to the Air Permeance Tester

The TQD-01 Air Permeance Tester is a state-of-the-art instrument designed for precise measurement of air permeance in paper and board materials. Utilizing the Schopper method, this advanced Air Permeance Tester is essential for evaluating the medium air permeance range, specifically for papers and boards with permeances ranging from 1×10⁻² to 1×10² μm/(Pa·s). This method is highly effective for standard paper products but is not suited for rough-surfaced papers, such as creped or corrugated types, which may cause clamping issues and air leakage.

Features of the Air Permeance Tester

• Versatile Application: The TQD-01 Air Permeance Tester is not limited to just paper; it is also suitable for various materials including cement bag paper, paper bag paper, cable paper, copy paper, and industrial filter paper. This flexibility makes it a valuable tool for a wide range of industries and applications.

• Accurate Measurement: This Air Permeance Tester ensures high accuracy in measuring the mean flow of air through a unit area under a specific pressure difference. The results are expressed in micrometres per pascal second [1 μm/(Pa·s) = 1 mL/(m²·Pa·s)], providing reliable data for quality control and material analysis.

• Reliable Testing Principle: The TQD-01 operates by clamping a test piece between two airtight circular gaskets. The absolute air pressure on one side of the test area is maintained at atmospheric pressure, while a constant pressure difference is applied across the test piece. This setup allows for the accurate determination of air flow through the test area within a specified time frame.
