Universal Testing Machines with Custom Testing Solutions
Application
This differential pressure tester is used for measuring the differential pressure on both sides of surgical masks or other fabric materials during gas exchange to test the breathability.
Features
1.This tester adopts uses a gas source that can continuously pressurize the sample without being limited by the space of the test site.
2. With high precision differential pressure sensor, the pressure difference can be digitally displayed on both sides.
3. It is equipped with special sample grip to hold the sample
