HV-5Z/10Z/30Z/50Z Vickers hardness tester

Product Overview

The HV-5Z / HV-10Z / HV-30Z / HV-50Z Vickers Hardness Tester is a classic medium-load mechanical hardness testing device. It adopts pure mechanical precision control + optical manual measurement, abandoning complex electronic digital modules. With simple structure, ultra-low failure rate and low maintenance cost, it is widely used in workshops, basic laboratories and teaching scenarios.

HV-5Z: Test force 0.2-5 kgf, high-magnification model for fine precision testing
HV-10Z: Test force 0.3-10 kgf, general-purpose medium-load model
HV-30Z: Test force 0.5-30 kgf, industrial conventional medium-load model
HV-50Z: Test force 1-50 kgf, full-range medium-load heavy-duty model

All models comply with GB/T 4340.1, ISO 6507-1, ASTM E92 international standards, covering 5-3000HV full hardness range.

Core Advantages

Stable Mechanical-Driven Performance

Pure mechanical transmission structure with no electronic components, avoiding failures caused by circuit damage and data drift. High-rigidity cast iron body features anti-vibration and anti-deformation performance, stably operating in dusty and slightly vibrating workshop environments.

Precise Medium-Load Hardness Testing

Covers complete medium-load test force range (0.2-50kgf), load accuracy up to ±1%. Equipped with reinforced diamond square pyramid indenter, it ensures regular square indentation without directional error, accurately testing thick-wall components, forgings, castings and surface-hardened layers.

Optical Eyepiece Measurement, Easy to Operate

High-magnification optical observation system (100X-400X), manual indentation measurement with intuitive operation steps. No professional digital system training required, suitable for on-site workshop testing and university engineering teaching.

Intelligent Automatic Function Configuration

Automatic loading, dwell and unloading process; automatic switching of objective lens and indenter. Built-in printer, USB & RS232 data interfaces support test data output and export.

Wide Application & Cost-Effective

Low long-term failure rate and low maintenance cost, ideal for medium-low frequency hardness testing of medium-large workpieces, coarse-grained materials, and conventional quality inspection scenarios.
