Principal Features

1. adopts a vitreous cylinder for supplying gas. The pressure in the cylinder can keep constant by mercury packing technique when a removable piston moving in the cylinder.

2. can supply float flowmeter and electronic soap film flowmeter for measuring the gas flow ranging from 1 to 20ml/min;

3. adopts the controllable induced circuit to start and close the tester, acquire the experimental data;

4. adopts the self-air supply to realize steady pressure at the entrance of core instead of high pressure cylinder.

Key Technical Parameters

1. measuring range: 0.01～6000×10^-3/um²

2. core size: Ø 25×25～80mm

3. measurement error: ≤2％
