HMV-2/2T
Micro Hardness Tester  显微硬度计

上海思汉仪器仪表有限公司https://www.seekhigh.com/

The micro hardness tester is a piece of equipment that is indispensable to metallographic research, product quality control, and the creation of product certification materials.

For this type of work, it is important to be able to measure the hardness of small parts and metallic structures used in precision equipment, processed surface layers, metal plating layers, etc. This type of measurement must be performed on a limited small area with small damage to the area being measured, and must yield extremely reliable results.

The HMV Series hardness testers have been designed to meet these demanding conditions, providing outstanding performance with ease of use and user friendly design.
