The DRK108 electronic tear tester is a special instrument for the determination of tear strength. This instrument is mainly used for the determination of paper tearing, and can also be used for the tearing of lower-strength cardboard. It is used for paper-making, packaging, scientific research and product quality. Ideal laboratory equipment for supervision and inspection industries and departments. Features 1. Modern design concept of mechatronics, compact structure, beautiful appearance; 2. Adopt modular integrated thermal printer, fast printing speed, easy to change paper; 3. Chinese-English bilingual operation menu (Chinese-English), which can be switched at any time; 4. Multi-function and flexible configuration: The instrument is mainly used for paper and cardboard measurement. Changing the configuration of the instrument can be widely applied to the measurement of other materials; 5. Obtain the measurement results directly: After completing a set of tests, it is convenient to directly display the measurement results and print the statistical report, including the average value, standard deviation and coefficient of variation; 6. Adopt 24-bit high-precision AD converter (resolution can reach 1/10,000,000) and high-precision weighing device to ensure the rapidity and accuracy of instrument force data collection; high measurement accuracy. Applications The instrument is mainly used for paper measurement. Changing the configuration of the instrument can be widely used for the measurement of other materials, such as plastic, chemical fiber, and metal foil.
