This instrument is used to measure the internal tear resistance or tearing degree of the paper. The working principle of the instrument is based on the work consumed by tearing the test sample to a certain length. Under normal circumstances, 16 sheets of paper overlap each other The tear test was carried out together. Therefore, dividing the total work consumed by tearing these papers by the product of the number of tearing samples and the tearing distance, the quotient is the force required to tear a sample, expressed in grams. The scale and scale of the instrument are engraved according to the condition of 16 tearing samples with a tearing distance of 86 mm (the tearing length of the sample is 43 mm and the tearing distance is twice).
The instrument is easy to operate, reliable in performance and advanced in technology. The test data is displayed digitally and the printer prints the test report. It is an indispensable ideal equipment for scientific research units, paper manufacturers, packaging industry, and quality inspection departments.
