ZB-SL Tear Strength Tester is a special instrument for measuring paper tearing, mainly suitable for the determination of tear degree of various types of paper, and can also be used for the determination of tear degree of lower strength cardboard, and is a satisfactory testing equipment for papermaking, packaging, quality inspection institutions and other departments.
1. High precision
The high-precision sensor is used to make the resolution reach 0.1mN, and the test accuracy error is within ±1%. This instrument is a tear meter with high accuracy in CHINA, and the user can use self-equipped weights for value verification.
2. Good stability
The included weighing weights are easy to calibrate at any time, and the built-in pendulum friction compensation reduces the impact of friction on the test, resulting in more accurate and stable results.
3. Easy to use and easy to operate
Large-screen color touch screen display, friendly man-machine interface operation, fully automatic completion of the test, with test data statistical processing function, micro printer output. The automatic pendulum release control and the automatic memory and display of the results reduce human error, which is not only easy to operate, but also makes the results stable and correct.
4. It is convenient for measurement and calibration
The instrument is equipped with special calibration weights and a built-in calibration program, which is convenient for the metrology and calibration department (third party) to calibrate the instrument. During calibration, enter the calibration test program and screw the calibration weight into the calibration screw hole, and the indication error can be easily calibrated.
