The Digital Tear Tester is an instrument that utilizes the Elmendorf testing method to measure the tear resistance of test samples. The RF3259HU model features an ultra-high range of 256N and adopts advanced technological concepts, offering functions such as automatic range recognition and switching, automatic swing arm return, pneumatic brake, friction compensation, center of gravity deviation compensation, and built-in calibration. It is equipped with computer software for convenient report export and data transmission. Additionally, it can be configured with IoT (Internet of Things) functionality to enable remote data transmission, backup, and other functions.
