Micro Vickers hardness tester QHV series

benchtopfor thin sheet materialglass

Product overview
The QHV-5/10/30/50TPTA series is a fully automatic digital Vickers hardness tester integrating mechanical, optical and computer systems. It performs automated loading/holding/unloading, supports multiple interfaces (Ethernet, Bluetooth, RS232) and provides data recording and traceability. Intended for hardness testing of thin hardened layers and small/precision specimens such as micro-components, thin sheets, metal foils, wires, electroplated coatings, nitrided layers, and non-metallic materials (glass, jewelry, ceramics).
