ASTM D 1424 Fabric tear tester/Paper Elmendorf Tearing Tester/Plastic film tear strength testing machine
Introduction
Elmendorf tear tester/elmendorf tear strength tester/elmendorf tearing strength tester is used for testing tear strength of sheet materials such as paper and plastic film, composite film, textile and non-woven cloth.The pre-cut specimen is continued to be torn to the average force required for a certain length.The instrument is equipped with an optical rotary encoder to measure the swing Angle position of the tear during operation.

Character
The high precision Angle sensor is adopted to make the resolution up to 0.1mn and ensure the test accuracy error within 1%. The instrument is currently the most accurate one in China, and users can use the self-equipped weight to test the tear degree.
The attached weighing weight can be easily calibrated at any time, and the built-in friction compensation device of the pendulum shaft reduces the influence of friction on the test, making the result more accurate and stable.
LCD English display, friendly man-machine interface operation, automatic test completion, test data statistical processing function, printer output, automatic pendulum release control and automatic memory and display of results, reduce human error, both easy to operate, but also make the results stable and correct.
The instrument is equipped with a special calibration weight and built-in calibration procedure, which is convenient for the measurement and calibration department (a third party) to calibrate the instrument. When calibrating, enter the calibration test procedure and screw the calibration weight into the calibration screw hole for easy value indicating error calibration.
