Application
Standard
EN 14683
Functional advantages
Built-in touch screen and micro printer
High-precision differential pressure sensor, digitally displays the differential pressure across the sample
Manual control of air flow and time
Pressure sensor, gas quality controller can be calibrated and measured
Theoretical method
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 is detected by a pressure sensor, and the pressure difference is calculated.
