Instrument characteristics:

1. Mitsubishi 16 bit microcontroller control, strong anti-interference ability, can store data 99 times;

2. Adopting a microcomputer control system, high-precision pressure sensors, digital feedback adjustment of suction air volume, automatic tracking, measurement and display of pressure difference at each point, with extremely high stability and reproducibility;

3. All test nozzles are calibrated point by point throughout the full range, resulting in more accurate test data. The test nozzles are made of high-quality stainless steel material, which has a long service life;

4. The test data is directly displayed on a high-definition display screen, without the need for manual table lookup and calculation. It can display various set values, freely convert air permeability and air permeability, and improve testing efficiency;

5. Equipped with a printer interface to print and output test reports (YG461D).
