1.Scope of pressure needle route:0~2.5millimeters.

2.The scale value:0-100 degrees.

3.The force of pressure needle end:550mN~4300mN（56~438.5g). 

The method of using 

 Held the middle of the instrument,located the hardness tester gently on the plane

Specimens which is bigger than presser foot(orspecimen).Reading out the value in

1 second when durometers’presser foot contact with the samples moothly.And the tick

of pointers is the hardness value of sample (specimen). In order to improve the

accuracy of measurement, you should putthe sample on a flat plate glass or plate.

Each measuring point should be measured only on
