Paper Tear Tester

PN-TT1000F Paper Tear Tester is an electronic paper and cardboard tear detection instrument designed and developed according to relevant standards, which is suitable for the tear determination of various types of paper, and can also be used for the tear determination of lower-strength cardboard materials. Tear degree is an indicator of the mechanical strength and physical properties of paper and cardboard, and refers to the average force required to tear the pre-cut specimen to a certain length, in millinewtons (mN).
Working Principle: A stack of specimens (usually 4 layers) with a defined pre-cut is torn apart by a moving plane pendulum perpendicular to the specimen face to tear the paper a fixed distance. The potential energy loss of the pendulum is used to measure the work done in the process of tearing the specimen.
