Description
Air flow resistance tester GBN701 used for face mask air flow resistance and differential pressure testing to check breathability and can also be used to check differential pressure of textile materials gas exchanger.
Principle
The output of the air flow is set by a gas flow meter, the air flow passes through a certain area of the test sample, the current pressure if detected by a pressure sensor, and the pressure difference is calculated.
Standards: YY0469-2011, YY0969-2013
Features
- Equipped with special sample grip, easy to use
- Built-in HD touch screen
- Built-in micro printer, easy to print test results
- Equipped with high-precision differential pressure sensor, digitally display the pressure difference between the two sides of the sample
- Equipped with high-pressure gas flow control, real-time digital display of air flow to stably control air flow, manually setting available
- Test time can be adjusted according to test requirements
Specifications
- Gas source: Compressed Air
- Air flow: Adjustable 1 – 10L/min (Standard air flow 8L/min)
- Sample size: phi 25
- Differential pressure sensor range: 0 ~ 500Pa
- Display mode: touch screen
- Power supply: 220V, 50Hz
