*HR150S can be used directly to measure Rockwell hardness for plastic material.
*Provided with many features such as high measuring precision, wide measuring range with 15 Rockwell scales.
*Automatic test force switch according the selected scale without manual operation.
*Automatic load cycle. The loading, dwell, unloading process of the main test force are controlled exactly to meet standard.
*Measuring results digitally displaying and can be printed, or transmitted to external computer automatically.
*The recovery time can be setted according to deformation of different plastic materials from 1-50 sec.
* Upper/lower limits setting & alarming
* Curved surface correcting automatically
*The tester meets all the following standard such as ISO 2039, and ASTM D785.
