Introduction: The LBT Paper Tearometer is a proprietary instrument for determining the tear strength of paper. It is suitable for the determination of tearing degree of all kinds of paper and also can be used for tearing degree of lower strength cardboard. Work environment requirements: 1. Workbench is solid, easy to work for benchmarking. 2. The working environment is clean, clean the air less dust. 3. No vibration Executive Standard: ISO1974 "paper - Determination of tear (Aidendorf method)" GB455.1 "Determination of paper tear" Technical Parameters: 1. Measuring range: (10 ~ 1000) mN, of which a) Standard pendulum (10 ~ 1000) mN, indexing value 10 mN b) Light pendulum (10 ~ 500) mN, indexing value 5 mN c) The lightest pendulum (10 ~ 200) mN, sub-degree 2 mN d) The instrument is equipped with standard pendulum. (Light pendulum, the lightest pendulum special order according to user requirements) 2. Indication error: ± 1% within 20% ~ 80% of the upper limit of measurement, ± 0.5% FS outside the range. 3.
