Product introduction: DRK127 touch color screen friction coefficient tester (hereinafter referred to as the measurement and control instrument) adopts the latest ARM embedded system, 800X480 large LCD touch control color display, amplifiers, A/D converters and other devices adopt the latest technology, with high precision and high precision. The characteristics of resolution, simulating the microcomputer control interface, simple and convenient operation, greatly improving the test efficiency. It is an instrument for testing the friction properties of materials, a necessary testing instrument for material manufacturers and quality inspection departments, and an indispensable testing instrument for scientific research units to conduct new material research. DRK127 touch color screen friction coefficient tester (suitable for measuring the static friction coefficient and dynamic friction coefficient of plastic film and sheet, rubber, paper, cardboard, fabric and other materials when sliding. 2. Features: 1. The force-time curve can be displayed visually during the test; 2. At the end of a test, the static friction coefficient and the dynamic friction coefficient are measured at the same time 3. A set of 10 test data can be automatically recorded, and the maximum, minimum, average, standard deviation, and coefficient of variation can be calculated at the same time; 4. The vertical pressure (slider quality) can be set arbitrarily; 5. The test speed is continuously adjustable from 0-500mm/min; 6. The return speed can be set arbitrarily (significantly improve the test efficiency); 7. The reference data for the determination of dynamic friction coefficient can be adjusted according to the actual situation; 3. Main technical parameters 1. Force measurement resolution: 1/100000 2. Force measurement accuracy: <0.1% 3. Sampling frequency: 20Hz 4. LCD display life: about 100,000 hours 5. The number of effective touches of the touch screen: about 50,000 times 6. Data storage: 511 sets of test data can be stored, recorded as batch number; Each group of experiments can be carried out 10 times, which is recorded as a number. 4. meet the standards: GB/T 10006 "Method for Determination of Friction Coefficient of Plastics and Sheets" FZ/T 01054-2012 "Test method for surface friction properties of fabrics"
