Paper Permeability Tester

For paper and board Determination of air permeability(Schopper method). The average air flow per unit area of paper or paperboard under unit time and unit pressureunder specified conditions.

Product features

The design principle of differential pressure method, the sample pre processed on measuring surface, forming a constant in the sample on the pressure difference in the gas pressure under the action of the high side to the low side flow through the sample, according to the flow area of the sample, the pressure and flow, calculate the permeability of the specimen.

According to the traditional structural design, processing and assembly, universal, easy to use and easy to understand, manual compression, good sealing.

The main parts of contact water are processed with brass and stainless steel to ensure the durability and non rusting of the instrument.
