Face Mask Air Flow Resistance and Differential Pressure Tester GBN701

Features :

The instrument uses a gas source that can provide (20±1)kPa pressure to continuously pressurize the sample withoutbeing limited by the space of the test site.
The instrument has a pressure gauge to display the pressure, the pressure can be adjusted.
Use pressurized medium:compressed air.
The special stainless steel penetrating tests lot ensures that the sample is firmly clamped and the synthetic blood is prevented from splashing around.
Square metal barrier net:open space ≥ 50%; bending ≤ 5mm at 20kPa.
Digital display timer, accuracy ± 1 second.
The instrument has a clamp that can generate 13.5 Nm torque.
