PTC®410硬度ASTM O型
測(cè)試軟橡膠，彈性體，而且很軟塑料的硬度
PTC®的Model410的ASTM O型硬度計(jì)測(cè)量軟橡膠，軟印刷輥，紡織繞組，以及其他類似的材料的硬度。型號(hào)410達(dá)到或超過美國(guó)測(cè)試和材料協(xié)會(huì)（ASTM）D2240規(guī)格。
該儀器具有低眩光系列化表盤搭配大膽，容易閱讀的數(shù)字。硬度計(jì)有一個(gè)zui大保持手即保持峰值讀數(shù)直到復(fù)位。每個(gè)硬度計(jì)配有一個(gè)試塊和手提箱。
PTC® 410 Durometer ASTM Type O
Test the Hardness of Soft Rubber, Elastomers, and Very Soft Plastics
PTC®'s Model 410 ASTM Type O Durometer measures the hardness of soft rubber, soft printing rollers, textile windings, and other similar materials. The Model 410 meets or exceeds American Society for Testing and Materials (ASTM) D2240 Specifications.
The instrument features a low glare serialized dial with bold, easy to read numbers. The durometer has a Max Hold hand which maintains the peak reading until reset. Each durometer comes complete with a test block and carrying case.
