1 . Usage:

Foam Tear Resistance Test Machine is used to test the tensile strength , tearing force , peeling and adhesive force- the physical property of strength resistance .

2 . Theory :

Foam Tear Resistance Test Machine adopts the electronic tensile meter , use the motor to make displacement of the fixture .
Place the fixture with sample between the upper and lower fixture , use a given speed to pull the upper fixture upward , and the upper load cell with sensor the tensile strength , and convert the strength into voltage sign and output to the display screen . And the strength value will be displayed automatically .

3. Instruction:

1 . Power switch : main switch of the machine

2 . Power indicator light : The power indicator light will be on when power on . It will be off when power off or electricity is not ok .

3 . Emergency switch : This key can help to stop the machine immediately when there is an abnormality .

4 . Speed adjuster : the speed adjust button to pull the upper fixture

5 . Upper and lower fixture

6 . Length sensor : it will sensor the resistant strength when the lower panel goes upward , and will output the strength to the display screen .
