– This machine was developed with KRK’s own technology to test the tear strength of thin paper sheets, synthetic paper, cellophane or the like
– The maximum tear energy is 1/3 or 1/4 of the standard type (selectable). (option 1/16 satndard)
– The position of the chuck is the same as the standard type: the chuck is 27.5 degrees from the vertical line passing the rotation axis with a rotation radius of 104 mm
– Pendulum capacity : 0 to 300mN

– Gloss is one of the important factors for printing paper; the reflection at 75 degrees is wide spread for general uses, except for papers of high gloss. The principle of this machine is as follows: Gloss amount of normal reflections is measured by irradiating light beams to the specimen at 75 degrees
– Incidence angle: 75±1°
– Life of lamp: approx, 10,000 hours
– Standard plate: one plate, black-colored

JIS P-8142

– Vapor permeability is expressed by the mass of vapor that passes through a unit area of specimen at a certain temperature and humidity.
– This tester measures the quantity of water transmission. Test procedure: put silica gel in an aluminum cup, and close the cup with a specimen; leave them at 40℃, 90% RH for a certain span of time, to measure the mass (in grams) of vapor transmission.
– Components 12 aluminum cups, 12 glass Petri dishes, 12 aluminum rings, 1 cup base, 1 guide, 1 weight about 500g
– Accessory wooden case
