【 scope of application 】
This machine uses the Gerlach method for measurement, suitable for measuring paper and cardboard (with air permeability of 0.1-100μm/(pa.s) in the papermaking industry, battery separators, tuning paper, medical materials, plastic films, and other products. It measures the average air flow per unit area of paper or cardboard under a specific time and pressure difference, with the test results expressed in micrometers per Pascal per second.

【 meet a criterion 】>
GB/T458-2008 Determination of air permeability of paper and board (Gelley air permeability) GB/T 5402-2003 Paper and board Permeability determination (medium range) Gerlai method ISO5636-5-2013 Paper and board-Measurement of permeability and air resistance (medium range) -Part 5: Gerlaffe

【Instrument Effects】
1. Equipped with a 7.8-inch large color touch screen and menu mode

2. Reduce the pressure by importing high precision regulating valve to effectively protect the safety of the tested components;

3. High precision sensor is used to collect the test pressure, and the test pressure is fed back in real time with sensitive response;

4. Use air quality flowmeter with higher stability performance to monitor the leakage of sample gas;

5. The sample is clamped by pneumatic method, and the sealing device is used to ensure that the sample is tightly attached without leakage;

6. Configure a mini printer to print data reports directly;
