Paper testing device air permeability “BP-2T”
The device for testing paper for air tightness VP-2 is designed to determine the air permeability of paper in accordance with GOST 13525.14-77.
The principle of operation of the device is to measure the air volume of a sample of paper that has passed through the measuring area, per unit time at a certain vacuum under the sample.
The upper limit of the vacuum index, kPa 1.0
The price of the distribution of the scale of the vacuum index, kPa 0,01
