Knoop/Vickers hardness tester QHV-1000TPTA

micro Vickersbenchtopfor thin sheet material

Product Overview This QHV-1000TPTA micro‑Vickers hardness tester integrates mechanical, optical and computer technologies to perform fully automatic HV/HK hardness testing with digital display. It supports automatic turret switching (objectives and indenter), automatic diagonal measurement input from images, automated hardness calculation, data storage, display, printing and hardness conversion. It is designed for small metal parts, thin sections, metal foils, hardened layers and surface treatments (electroplating, nitrided, carburized, cyanided) as well as non‑metallic materials (jewellery, ceramics, glass) that require low test forces.

Key Functional Summary Image‑processing microhardness tester with a high‑precision automated stage enabling autofocus, automated loading/holding/unloading, programmable point patterns and automated reporting. Results and images can be exported or transmitted over a network for laboratory workflows and QA traceability.

Product Advantages

• Automated operation: autofocus, turret switching and automatic indentation imaging/measurement for repeatable results.
• Integrated control: PC‑based software with mouse operation and report generation.
• Flexible stage control: manual, electric or computer control for X, Y and lift movements.
• Panoramic scanning: generate surface panorama to locate test points quickly.
• Surface correction: multiple correction modes to reduce curved‑surface testing errors.
• Multidimensional analysis: hardness conversion methods, real‑time curves and statistical summaries.
• Customisable test programs and reports: user‑defined test types, parameters and data layout.
• Carburized‑layer analysis: automatic calculation and presentation of carburized layer depth based on hardness threshold.
• Networkable data handling: automatic calculation, storage, printing and electronic report export.
