Description
Summary:
The instrument is suitable for the determination of medium air permeability range of 0-1000ml/min paper and board. The structure parameters and technical properties of the instrument are in accordance with relevant standards and requirements of QB/ T1667-98 “paper and cardboard breath-ability tester” and GB/ T458-1989 “paper and cardboard breath-ability determination method” (Schopper).
Standard:
ISO5636: Paper and board — Determination of Air Permeance (Medium range)
GB/T458: Paper and board — Air Permeance Tester
Features:
- Accurate test result;
- With excellent durability
- Easy and convenient to operate;
- Can get the test result through the formula (Ps=V/P . t) (Ps: air permeance (μm/(Pa·s),
5: volume of air passing through the test piece(ml), ΔP: pressure difference (kPa), t: test time(s).
