美国PTC一般硬度橡胶硬度计409C硬度ASTM C型

PTC®409C硬度ASTM C型

测试中硬橡胶，合成橡胶和热塑性塑料的硬度

示范409C C型硬度计是用来测量ASTM（美国试验协会和材料）类型C硬度。这包括材料如：橡胶，合成橡胶，和其它类似橡胶的材料包括氯丁橡胶，硅酮，乙烯基，和丁基。软塑料，油毡，皮革及类似材料一般都属于这一范围相同。 PTC®的型号409C达到或超过目前ASTM D2240规格。准确的读数可以在任何位置获得。

PTC® 409C Durometer ASTM Type C 

Test the Hardness of Medium Hard Rubber, Elastomers, and Thermoplastics 

The Model 409C Type C Durometer is designed to measure ASTM (American Society for Testing and Materials) Type C hardness. This includes materials such as: rubber, elastomers, and other rubber-like materials including neoprene, silicone, vinyl, and butyl. Soft plastics, felt, leather, and similar materials generally fall into this same range. PTC®'s Model 409C meets or exceeds current ASTM D2240 Specifications. Accurate readings can be obtained in any position.
