Product Details
Medical Facial Mask Gas Exchange Pressure Difference Testing
Machine
1. Products description:
Mask Gas Exchange Pressure Difference Testing Machine is based on the test principle of the standard YY0469-2011
"Technical Requirements for Medical Surgical Masks". The
differential pressure sensor is used to achieve the pressure
difference between the internal pressure and the external pressure
of the mask. The test item is equipped with a special tooling
device to achieve the test tightness of the product. It is mainly
applicable to the measurement of the gas exchange pressure difference of medical
surgical masks / mask woven fabrics. It can also be used to determine the gas exchange pressure
difference of other textile materials.
2. Application:
--- Determination of gas exchange pressure difference between
surgical masks/woven masks.
--- Determination of gas exchange pressure differences of other
textile materials.
3. Meeting Standards:
Yy0469-2011 Technical Requirements For Surgical Masks For Medical
Use
4. Features:
- The vacuum pump is used to realize the power source of the test
product, which is not limited by the space of the test site.
- Equipped with high precision differential pressure sensor, digital
display of the differential pressure on both sides of the sample;
- The case adopts the form of all-in-one machine with built-in vacuum
pump and digital display meter to realize automatic pressure
detection and automatic display.
- The internal and external pressure measurement of the product is
realized by means of tooling and fixture, with built-in
differential pressure sensor.
- Equipped with special jig, convenient to load and test products.
