ZB-SL Electronic tearing tester
Introduction
ZB-SL Electronic tearing tester is a special instrument to measure the tearing degree of paper.it is mainly used to measure the tearing degree of various kinds of paper.it can also be used to measure the tearing degree of lower strength paperboard.it is an ideal testing equipment for paper making, packaging, quality testing institutions and other departments.
Features
1. High accuracy
High precision sensor is adopted to make the resolution force up to 0.1mn and ensure the accuracy error within ±1%.This instrument has the highest precision in China, and can be used by the user to check the tearing degree.
2. Good stability
With the weight, it can be easily calibrated at any time. The built-in pendulum shaft friction compensation device reduces the impact of friction on the test, making the results more accurate and stable.
3, easy to use, easy to operate
Large screen color touch screen display, friendly man-machine interface operation, automatic completion of testing, test data statistics processing function, micro printer output.Automatic pendulum release control and results of automatic memory and display, reduce human error, not only easy to operate, but also make the results stable and correct.
4. Easy to measure and calibrate
The instrument is equipped with a special calibration weight and built-in calibration procedure, which is convenient for measurement and calibration departments (third parties) to calibrate the instrument.During the calibration, enter the calibration test program, screw the calibration weight into the calibration screw hole, and the calibration error calibration can be easily carried out.
