Đồng hồ đo độ cứng cao su, nhựa PTC Shore C Scale e2000 Durometer 502C
C Scale Durometers Measure the Hardness of Medium Hard Rubber, Elastomers, and Thermoplastics.
The design of the e2000 is the ultimate in hand held hardness measurements. Easier handling and more repeatable readings are the result of PTC®'s Ergonomic Research. The durometer is easy to grip and the 1.25 diameter base has a large landing area for increased stability and maximum repeatability.
