Equipment Overview: microcomputer and control tear paper tear strength tester is dedicated measurement instruments, this instrument is mainly used to determine the degree of torn paper can also be used for a lower tear strength cardboard determination. The main functions: it works: instrument design based on functional principles. In a position to be a certain potential to tear the pendulum is released, the potential energy into kinetic energy, and the tear sample acting. The force required to tear the specimen (reflecting the rotation angle of the fan-shaped pendulum) by high-precision optical shaft encoder input is converted to an electrical signal control circuit after circuit processing mode to display or print output. Main features: The instrument is mechatronics test apparatus, computer monitoring and control system uses high-precision optical rotary encoder and a microcontroller as the core of the digital circuit technology, operating tips and cotton panel LCD Chinese display by typing commands to achieve a simple interactive, with advanced technology, fully functional, stable performance, easy operation, etc., is paper, packaging, research and product quality supervision, inspection and other industries and sectors ideal laboratory equipment. Meet the criteria: performance parameters in line with ISO1974 "Paper - Determination of tearing resistance (Elmendorf love Lee Law" and GB455 relevant provisions of a "paper tearing assay" and other industry standard applications:?.
