The unit is supplied complete with - Lifting Handle Sample Punch, Adopter plate 2, 2 weights, 3 clamping plates. Air, at a low, uniform pressure is forced downward through an open tube to the upper orifice plate against which the sample is clamped. Each 50cc of air is marked and the test consists of timing the amount of air used in any of the three ways listed below:
SMOOTHNESS TEST
Lateral flow between several sheets.
POROSITY TEST
Rate of flow through one square inch.
SOFTNESS TEST
Rate of flow over the surface which has been constructed by a given weight.
Uniform clamping pressure is provided by a lever arm, to which weight can be attached.
The instrument conforms to the following standards:

 

APPLICABLE STANDARD
TAPPI T 479 , TAPPI T 460 , TAPPI T 490 , ASTM D 726 , SCAN P 53,
SCAN P 19, APPITA P 420, CPPA P 14

 

OPTION:

Electronic self starting timer as an optional accessory, for automatic measuring of either 25, 50, 100, 150, 200 or 300cm3 air to pass through the test specimen. The timer starts automatically when the zero slit of the graduated ruler pass an optional read fork and stops automatically as soon as the predetermined volume of air has been passed through the sample.
