Product Description
The CHV-5 Vickers Hardness Tester is an advanced optical–mechanical–electronic integrated system that uses a closed-loop loading control structure for highly stable and repeatable hardness measurements. The instrument features a high-definition optical system, dual optical channels, adjustable brightness, and a clear digital display. It supports direct input of indentation length and automatic calculation of hardness values. With its durable cast-aluminum body, scratch-resistant coating, and user-friendly interface, the CHV-5 is suitable for laboratory analysis, heat-treated samples, thin metals, hardened layers, carburized surfaces, coatings, and brittle non-metallic materials such as ceramics and glass.
Product Advantages
High-grade optical system provides bright, sharp imaging and can function as a simple microscope for microstructure observation.
Industrial display panel shows hardness scale, force, indentation length, dwell time, test count, and converted scales.
Cast-aluminum body ensures dimensional stability, long-term durability, and resistance to deformation and scratches.
Supports manual turret switching for fast transitions between observation, testing, and measurement points.
Closed-loop loading system keeps test force accurate across HV0.1–HV5 ranges, improving repeatability.
Dual optical channels (eyepiece + CCD camera) allow simultaneous viewing and measurement without switching paths.
Supports HV and HK test modes, automatic loading, adjustable dwell time (1–98 s), and measurement up to 9999 HV.
Application Range
Steel, non-ferrous metals, metal foils, thin plates, and carburized layers
Nitride layers, hardened surfaces, coatings, electroplated layers
Ceramics, glass, wafers, and brittle materials
Microstructure testing and heat-treatment hardness evaluation
