Short Description:

Product Detail

Product Tags

DRK108A Paper Tearness Tester is a special instrument for the determination of tear strength. This instrument is mainly used for the determination of paper tearing, and it can also be used for the determination of tearing of lower-strength cardboard. It is used for papermaking, packaging, scientific research and product quality. Ideal laboratory equipment for supervision and inspection industries and departments.

Features
Compact structure, convenient operation, beautiful appearance, convenient maintenance; multi-function, flexible configuration,
The measurement results are directly obtained, and the instrument is precisely manufactured and has high measurement accuracy.

Applications
The instrument is mainly used for paper tear measurement. Changing the configuration of the instrument can be widely applied to the measurement of other materials, such as plastic, chemical fiber, metal wire, and metal foil.
