I.Introduction:
A Durometer
It is designed for testing the hardness of soft rubber,printer roller and other elastomer material.(ASTM--D--2240)
D Durometer
It is designed for testing the hardness of hard rubber,such as:thermoplastic plastics,bowling,plastic floor and so on.(ASTM--D--2240)
O/OO Durometer
It is designed for the hardness of soft and elasticty material,spinning trunk rotation and soft grain structure materials.(ASTM--D--2240)

III.Notice:
1).Thickness of test specimen >6mm,no more than 3 layers; Test area >/=feet area(diameter 18mm).
2).Test 3 times and calculate the average as test result.
3).Usually,plz use A/D.When the hardness of A >90,plz use D or O.
