CHVS-100Z Digital Auto-Turret Vickers Hardness Tester

Product Description

The CHVS-100Z Digital Auto-Turret Vickers Hardness Tester is an integrated optical–mechanical–electronic instrument engineered for high-load micro-indentation testing up to 100 kgf. It adopts a closed-loop loading control system to ensure high force accuracy and excellent measurement repeatability across the entire HV1–HV100 range. Its large industrial LCD screen clearly presents indentation lengths, hardness values, dwell time, force levels, statistical averages, and real-time measurement status.
Equipped with a digital micrometer eyepiece, the instrument automatically converts indentation length to hardness with a single button press—no manual table lookup is required. The automatic turret enables seamless, repeatable switching among observation, loading, and measuring positions, while the rigid cast-aluminum frame and engineered optical path ensure long-term stability. The CHVS-100Z is designed for laboratories and industries that require high-force micro-indentation measurement on coatings, surface layers, metallic materials, and brittle substrates.

Product Advantages

1. Professional optical system designed by experienced optical engineers provides clear, bright micro-indentation images with adjustable illumination for precise contrast control.

2. Large high-resolution LCD displays hardness value, D1/D2 diagonal lengths, dwell time (1–99 s), force level (1–100 kgf), test count, average values, conversion scales, and date/time.

3. One-piece cast-aluminum housing provides excellent rigidity and thermal stability, ensuring minimal mechanical drift during long-cycle measurement.

4. Auto turret mechanism performs optical switching and position alignment automatically, improving repeatability and operator consistency.

5. Digital micrometer eyepiece directly confirms indentation length and produces hardness results without manual conversion tables.

6. Closed-loop loading system ensures stable force output through HV1–HV100 testing, improving accuracy across all load levels.

7. Dual optical channels (eyepiece + CCD) support simultaneous visual examination and digital image capture.

8. High optical resolution of 0.125 μm and a 400 μm measuring range support micro-indentation testing on thin layers, hard coatings, and metal substrates.

9. Optional built-in printer and PC-connected hardness software support automated data output, statistical processing, and reporting.

10. Designed for continuous laboratory operation with enhanced heat dissipation and long-term alignment stability.
