DRK106 Touch Screen Horizontal Cardboard Stiffness Tester is an instrument for testing the bending strength of paper boards and other low-strength non-metallic materials. This equipment is designed in accordance with GB/T2679.3 "Paper and Cardboard Stiffness Test" and is suitable for ISO249. 3 "Determination of Stiffness of Paper and Cardboard", the measuring principle of the instrument meets the requirements of ISO 5628 "Paper and Cardboard—Determination of Static Bending Stiffness—General Principles", and it is also suitable for the determination of other types of cardboard. 【Applications】 Generally 20 mN-10000mN (the equivalent bending moment is 2 mN.m-1000mN.m) of paper and cardboard, it is also suitable for some materials with higher stiffness. 【Product Parameters】 Parameter item technical index Measuring range Bending force (15～300) mN, resolution 0.1 mN Accuracy of indication: Error of indication is less than 50mN ±0.6mN, the remaining ±1%, variability of indication ≤1% Bending length (50±0.1)mm, (25±0.1)mm, (10±0.1)mm Bending angle 15º±0.3º, 7.5º±0.3º Bending rate 200º±20º/min (adjustable) 【Working Environment】 Temperature: 20ºC±10ºC. Power supply: AC220V±5% 50Hz, the power supply should be grounded reliably. If the power supply voltage fluctuates beyond the above range, a power supply regulator should be used. The working environment is clean, there is no strong magnetic field vibration source, and the working table is flat and stable.
