Overview
YN-TQD02 electronic Air Permeability tester is a general-purpose electronic paper Air Permeability tester. Its technical requirements and detection methods meet the requirements and regulations of GB/T 22819 "Determination of high breathability of paper" and other standards. It is a professional instrument for detecting the breathability performance of paper, film, fiber weaving, filter materials and other sheet materials. It is a professional Air Permeability measurement instrument in the domestic paper industry, Spinning & weaving industry, and leather industry.
Features
1. Microcomputer Control system, high definition touch screen display, one click to complete the operation.
2. Imported High Accuracy Pressure and Differential Pressure Sensor to ensure accurate data.
3. Digital feedback adjusts the suction volume, automatically tracks and displays the pressure difference per point.
4. It can accurately detect the ventilation performance of various samples, with small table difference and high accuracy.
5. Digital tracking two-way test function, the system automatically prompts to replace the Nozzle.
6. Use a high-speed micro printer or USP link to the computer A4 for Chinese printing.
Principle
Under specified conditions, the average air Flow rate per unit area of the sheet through the unit time and unit pressure difference, expressed in microns per Pascal [1μm/(Pa ･ S) ] = 1mL/(m2 ･ Pa ･ S).
Applications
Electrical Insulating Paper, Encasement Paper, Fiber Paper, filter paper, Fabric, Nonwoven Fabric, Film, Other Fiber Materials

Steps
1. Prepare the sample.
2. Select and install the appropriate Nozzle and Test Area.
3. Place the specimen in the test area.
4. Start the test with one click through Touchscreen.
5. The instrument automatically tracks the measurement and displays the results.
6. The system may prompt to replace the Nozzle.
7. Use a printer or connect to a computer to output the test report.
Notice
Please read the instructions carefully before use.
Make sure the power supply is AC 220V +/- 10V.
Select the appropriate Nozzle and Test Area based on the Specimen Type and Expected Air Permeability.
The thickness of the specimen should not exceed 15mm.
* Regularly use calibrated orifice plates to calibrate instruments to ensure measurement accuracy.
* Pay attention to the working environment of the instrument and avoid use under extreme Humidity conditions.
The instrument is heavier (100kg), so it is necessary to pay attention to safety when handling and placing it.
Non-professionals should not disassemble or repair the instrument themselves.
