CHVS-5Z Digital Auto-Turret Vickers Hardness Tester

Product Description

The CHVS-5Z Digital Auto-Turret Vickers Hardness Tester is a high-tech optical–mechanical–electronic integrated instrument featuring a closed-loop load control system to ensure high force accuracy and excellent measurement repeatability. The unit is equipped with a large industrial LCD display and a digital micrometer eyepiece, allowing direct viewing of test force, indentation length, dwell time, measurement count, conversion scales, and date/time. By simply pressing the eyepiece button after measuring the indentation, the hardness value is automatically calculated and displayed on-screen. The instrument supports automatic turret switching, enabling seamless shifting between observation, loading, and measurement positions for efficient and stable operation.

Product Advantages

1. High-resolution optical system designed by senior optical engineers delivers sharp, bright, distortion-free indentation imaging; illumination intensity can be adjusted to suit extended operation.

2. Large industrial LCD panel displays hardness values (four digits), diagonal lengths (D1/D2), dwell time (1–99 s), test force (0.1–5 kgf), measurement count, brightness levels, and conversion scales.

3. One-piece cast-aluminum housing ensures long-term rigidity, resistance to deformation, and superior surface durability with automotive-grade coating.

4. Automatic turret switching supports smooth transitions among the viewing, loading, and measuring positions, significantly improving operational consistency.

5. Closed-loop force control maintains high force accuracy across HV0.1–HV5 ranges, reducing human influence and improving repeatability.

6. Dual optical channels—eyepiece plus CCD camera—allow simultaneous visual observation and digital imaging without optical path changes.

7. Optical resolution reaches 0.0625 μm with a 200 μm measurement range, suitable for micro-indentation evaluation on thin layers and brittle materials.

8. Supports HV/HK modes, auto loading/holding/unloading, multilingual interface, and optional built-in printer output.

Application Range

• Suitable for micro-indentation testing of thin coatings, diffusion layers, and ultra-thin hardened surfaces.

• Applied in semiconductor substrates, micro-optics, and precision sensor materials.

• Ideal for hardness evaluation of miniature mechanical components, micro-molds, tool edges, and precision-fabricated parts.

• Used in research on brittle and high-value materials such as sapphire, ceramic composites, fine glass structures, and wafer-level components.

• Supports laboratory applications in micro-mechanics, failure analysis, materials development, and surface engineering.
