CHVS-30 Digital Vickers Hardness Tester

Product Description

The CHVS-30 Digital Vickers Hardness Tester is an optical-mechanical-electronic integrated system that adopts a closed-loop loading structure to maintain high force accuracy and excellent repeatability. Its industrial digital display clearly presents indentation length, hardness value, dwell time, force range, test count, and conversion scales. Equipped with a digital micrometer eyepiece, the instrument allows users to measure indentation diagonals and obtain hardness values instantly without manual lookup. The manual turret mechanism supports smooth switching between observation, loading, and measurement positions, ensuring stable and efficient operation.

Product Advantages

1. High-grade optical system designed by senior engineers provides bright, distortion-free images; illumination can be adjusted for extended use without eye fatigue.

2. Industrial display panel shows four-digit hardness values, diagonal lengths (D1/D2), dwell time (1–98 s), force levels (0.2–30 kgf), test count, brightness, and conversion scales.

3. One-piece cast-aluminum housing offers excellent rigidity, wear resistance, and long-term dimensional stability, retaining accuracy even with frequent operation.

4. Digital micrometer eyepiece enables direct indentation-to-hardness calculation, speeding up workflow and eliminating human reading errors.

5. Manual turret switching supports accurate mechanical alignment for viewing, loading, and measuring processes.

6. Closed-loop loading ensures precise force output across all HV0.2–HV30 test levels, greatly improving repeatability.

7. Dual optical channels (eyepiece + CCD) enable simultaneous visual inspection and digital recording.

8. Optical resolution of 0.125 μm and a 400 μm measurement range support micro-indentation testing on thin plates, coatings, and small components.

Application Range

• Suitable for hardness evaluation of precision-machined surfaces, thin metallic sheets, micro-formed components, and calibrated contact points.

• Ideal for surface-layer characterization in carburized, nitrided, refined polishing, and fine-grinding zones.

• Used for process verification on small parts such as electrical connectors, miniature mechanisms, spring elements, and micro-fabricated molds.

• Applicable to functional coatings, protective films, metal finishing layers, and localized surface-engineering research.

• Supports laboratory requirements in materials tuning, micro-force studies, structural integrity checks, and fine manufacturing inspection.
