Micro Hardness Tester ZHμ HD (Zwick Roell)

Jan 1, 0001

The Micro Hardness Tester ZHμ HD (Zwick Roell) is a high-precision instrument used in material science to measure the hardness of small samples with great accuracy. This microhardness tester utilizes an optical system to precisely measure the indentation created on the sample surface by a diamond indenter under a controlled load.

The system is equipped with a motorized stage, which enables automated positioning of the sample and the measurement of multiple indentations with high repeatability. The ZHμ HD automated microhardness tester can provide accurate and precise hardness measurements for a wide range of materials, including metals, ceramics, and polymers, making it a valuable tool in materials research, quality control, and production processes.
