Introduction: The instrument is based on China's national standard GB / T2679.5-1995 (Determination of paper and cardboard folding resistance), is a mechatronic structure, capable of double counting the number of samples under test automatically count. Features: The instrument is based on China's national standard GB / T2679.5-1995 (Determination of paper and cardboard folding resistance), is a mechatronic structure, capable of automatically counting the number of double folding test samples. The instrument uses photoelectric control technology can make the folding chuck automatically after each experiment homing, to facilitate the next operation. The instrument has a powerful data processing capabilities: not only able to double the number of single sample birefringence and the corresponding conversion, but also statistics of the same group of multiple samples of the experimental data, can be calculated with the maximum value of the same group of samples, Minimum, average and coefficient of variation, these data are stored in the microcomputer, and can be displayed through the digital tube. In addition, the instrument also has a print function. Technical Parameters: Measuring range: ≤1 mm; Counting range: 0 ~ 9999 times; Folding angle: 135 ± 2 °; Fold speed 175 ± 10 times / min; Folding head width of 19 ± 1mm, folding radius of 0.38 ± 0.02mm; Spring tension 4.91 ~ 14.72N, each 9.81N tension, spring compression at least 17mm; Fold the gap between the mouth of 0.25,0.50,0.75,1.00 mm; Overall dimensions: 360 * 300 * 325mm; Weight: 37.5kg; Power: 220V 50Hz; Power: 90W; Working conditions: room temperature 10 ℃ -30 ℃, stable workbench, table without vibration.
