To quickly and accurately determine the Smoothness, Air Porosity and Softness (or Compressibility) in paper and cardboard using the GURLEY method. This is the most popular and traditional model for the measurement of porosity / air permeability in medium value materials. Materials with lower air permeability can also be tested using optional plates with a smaller orifice diameter.
According to standards: TAPPI T460 - ASTM D 726 - APPITA / AS 1301-420 - BS 5926 - CPPA D.14 - ISO 5636/5 - NF Q 03-078 - SCAN P-19 y P-53

The Smoothness and Porosity Meter model S.P.S. 4190+4320 includes a 20-ounce cylinder, as well as a 1.0-square-inch air-hole bottom pinch plate and top adapter. This model is equipped with the 4320 Digital Module, it allows to control with great accuracy the time in seconds of the air passage through the sample and also to be able to connect the Smoothness and Porosity Meter to the LYNX System (Comprehensive Computerized Laboratory Management).
