Đồng hồ đo độ cứng cao su, nhựa PTC Shore D Scale e2000 Durometer 502D
Easier handling and more repeatable readings are the results 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.
The instrument uses a dial gauge with a full 360º scale with bold, easy to read numbers. The dial scale can easily be read to within a 1/2-point. Accuracy of the instrument is ±1 point. These durometers meet or exceed all aspects of ASTM D2240.
The 502D durometer and the 409D Ergo durometer were chosen as the standard by the Oil & Gas Industry for pipeline coating hardness.
