Product Description
The CHVS-30Z Computerized Digital Vickers Hardness Tester integrates an industrial PC, optical measurement system, automatic turret, and closed-loop loading technology to ensure stable force application, clear imaging, and high measurement accuracy. The large LCD displays diagonal lengths, hardness values, dwell time, test force, measurement count, and conversion results. The digital micrometer eyepiece automates hardness calculation without manual tables. The optional CCD imaging system enables computer-based indentation measurement, multi-point testing, depth-layer curve plotting, and data storage. The instrument is suitable for high-precision hardness testing of metals, thin layers, coatings, heat-treated layers, foils, and microstructures.
Product Advantages

Software Features
Hardening Curve: Allows users to manually input test point depths. The software automatically plots the hardening curve and calculates the case depth. For convenience, users can save multiple depth points to a template file for future use during testing.
Hardness Value Conversion, Correction, and Validation: The system can convert measured micro-Vickers hardness values to other scales (e.g., HB, HR). It can apply corrections for measurements on spherical or cylindrical surfaces and validate the effectiveness of sample measurements.
Data Statistics: Automatically calculates statistical values for measured hardness, including the mean, variance, Cp, and Cpk.
Automatic Alarm: Automatically flags values that exceed the set upper or lower limits.
Test Reports: Automatically generates test reports in Word or Excel format. Users can customize the report layout. Standard formats include individual hardness measurements, statistical values, indentation images, and the hardening curve.
Data Saving: Original measurement data and images can be saved into a single document.
Knoop Hardness & Fracture Toughness: The software can be configured for measuring Knoop hardness or fracture toughness.
Other Functions: Includes general-purpose features such as image capture, video acquisition, image processing, geometric dimension measurement, document annotation, photo album management, and fixed-magnification printing.
Applications
Suitable for metals, steels, alloys, foils, coatings, heat-treated layers, nitrided/carburized layers, microstructures, wafers, ceramics, and glass. Ideal for laboratories, research institutes, universities, and industrial quality control.
