It is suitable for the determination of tear strength (Elmendorf Method). It adopts single chip for data
detection and processing, pneumatic component performance process control, large-sized LCD dot matrix
display screen, which prompts operation procedures and tests data. With serial and parallel output, it can
output the detection report via printer, and also get connected with the computer.

Instrument structure and working principle:
SKZ156B Computer system control Elmendorf Tearing Tester1
2. Working principle:
Raise the hammer to a certain height to gain a certain potential energy; keep the movable and fixed
holders in line with the sample stuck in between, and the cutter will cut a hole in the middle of the sample.
When the hammer freely swung down, the moveable holder will quickly separated from the fixed holder, to
tear apart the sample by means of the stored energy in pendulum itself; from the remaining potential
energy of the pendulum obtained by the control system after the sample is torn, we can calculate the
energy consumed for tearing the sample, and thus get the force required during the tearing of sample.
