Absorbency Testing Device is used for determining absorption of liquid mediums, such as water, aqueous solutions, oils, varnishes and others at paper, card-board and corrugated board from the top and bottom sides within a predetermined time.
For water, this is affected according to DIN EN 20535, ISO 535, CPPAF 2, APPITA/AS 1301.411, F.E.F.C.O No. 7, SCAN P12, SCAN P37 and TAPPI T 441.
Pulp and Paper Testing Equipment consists of a base plate, on which a pillow block with an electronic stop-watch is located. The cylinder support and oscillating crank handle, which are rigidly mounted to each other, are arranged in a rotatable manner in the pillow block. The liquid recipient is located loosely in the cylinder support, so that it can easily be replaced. The lid is mounted to the cylinder support by hinges and is resiliently arrested on the liquid recipient by means of a locking device.
The initial tension of the spring is adjustable to enable testing of paper and cardboard with different thicknesses.
