CHVS-5 Digital Vickers Hardness Tester

Product Description

The CHVS-5 Digital Vickers Hardness Tester is an optical-mechanical-electronic integrated instrument that uses a closed-loop load control system to ensure high test-force accuracy and excellent repeatability. The digital display presents clear measurement information and supports energy-saving operation. Equipped with a digital micrometer eyepiece, the CHVS-5 allows users to view test force, indentation length, dwell time, measurement count, and conversion scales directly on the screen. By simply pressing the eyepiece button after measuring the indentation, the instrument automatically calculates and displays the hardness value in real time.

Product Advantages

1. Optical system designed by senior optical engineers provides bright, clear images; adjustable illumination reduces operator fatigue during long sessions.

2. Industrial digital display shows hardness value (4 digits), diagonal lengths (D1/D2), dwell time (1–98 s), force level (0.1–5 kgf), measurement count, brightness, and conversion scales.

3. Cast-aluminum housing formed in one piece ensures long-term structural rigidity, scratch resistance, and mechanical stability.

4. The CHVS-5 supports direct indentation measurement confirmation and automatic hardness value calculation without manual lookup.

5. Manual turret switching allows convenient transition between observation, loading, and measuring positions.

6. Closed-loop loading system ensures consistent force accuracy across HV0.1–HV5 ranges, improving repeatability.

7. Dual optical channels (eyepiece + CCD camera) allow simultaneous visual and digital observation without switching paths.

8. Optical resolution of 0.0625 μm and a 200 μm measurement range ensure precision in micro-indentation testing.

Application Range

• Suitable for micro-area hardness evaluation in electronic components, connectors, and precision parts.

• Ideal for measuring thin surface treatments such as sputtered films, PVD/CVD coatings, and ion-implanted layers.

• Used for hardness assessment of small mechanical parts, micro-gears, cutting tool edges, and miniature molds.

• Applicable for research on brittle materials including sapphire substrates, sensor wafers, optics, and ceramic micro-structures.

• Supports laboratory analysis for material development, micro-mechanical research, and fine manufacturing quality control.
