For testing the tear strength of sheet materials such as paper and plastic films, laminated films, textiles and nonwovens. The average value of force required to continue tearing a pre-notched sample to a certain length. (Measurement results are expressed according to the longitudinal or transverse direction of the initial incision of the sample, the unit is mN, the tear index is the tearing degree divided by the quantification of the sample, and the result is expressed in millinewton·square meter/gram mN·m2/g) The instrument is equipped with Optical rotary encoder to measure the swing angle position during tearing operation.
GB/T455, GB/T 16578.2 , ISO1974 , TAPPI T414 T496 , DIN EN 21974 , DIN EN ISO 6383-2 , DIN EN ISO13937-1
The high-precision angle sensor is used to make the resolution reach 0.1mN, to ensure that the test accuracy error is within ±1%, and the user can use self-made weights to verify the correctness of the tearing Tester;
The accompanying weighing weights can be easily calibrated at any time, and the built-in pendulum shaft friction compensation device reduces the influence of friction on the test, making the results more accurate and stable;
LCD Chinese display, friendly man-machine interface operation, fully automatic test, with test data statistical processing function, micro-printer output, automatic pendulum release control and automatic memory and display of results, reducing human error, easy to operate, and accurate results stable and correct;
The instrument is equipped with special calibration weights and a built-in calibration program, which is convenient for the measurement and calibration department (third party) to calibrate the instrument. When calibrating, enter the calibration test program, screw the calibration weight into the calibration screw hole, and it can be easily performed. Indication error calibration.
