A digital Vickers hardness tester is an advanced instrument used to measure the hardness of materials with high precision. Test force 0.3Kgf, 0.5Kgf, 1.0Kgf, 2.0Kgf, 3.0Kgf, 5.0Kgf. Digital type allows for faster testing and more consistent results, especially in laboratories or industrial quality control settings. Digital hv hardness tester combines traditional Vickers testing principles with modern digital technology to provide accurate, efficient, and user-friendly hardness measurements.
Manual Turret / Automatic Turret
- Manual turret tester requires the operator to rotate the turret by hand, which is simple, cost-effective, and easy to maintain. It's ideal for laboratories or educational settings.
- Automatic turret tester, on the other hand, rotate the lenses and indenter automatically. This minimizes user intervention, reduces potential mechanical errors, and improves testing efficiency, especially in high-volume or production environments.
- With robust construction and high-quality optical systems, digital Vickers hardness tester is built for long-term use. The manual turret offers mechanical reliability with minimal maintenance, while the automatic version reduces wear from manual handling.
- Both manual and automatic turret models can handle a wide range of test loads, making them suitable for metals, ceramics, thin coatings, and micro-components.
Digital VIckers Hardness Tester Equipped Built-in Printer
- One of the main benefits is the ability to print test results instantly after each measurement. This eliminates the need for manual data transcription, reducing the risk of human error.
- This streamlines the testing process, especially in high-throughput environments where multiple samples are tested consecutively. Operators can quickly generate printed reports for each sample, improving overall productivity and reducing administrative workload.
- Having a printer integrated into the hv hardness tester means fewer external components, saving space and reducing setup complexity.

Q1: What is the working principle of the Vickers hardness tester?
A1: The Vickers hardness tester measures a material's hardness by pressing a diamond-shaped pyramidal indenter (with a square base and 136° angles) into the specimen under a specific load. The load is applied slowly and held for a fixed dwell time, after which it is removed. The size of the resulting indentation is measured under a microscope, specifically the two diagonals of the square impression. The Vickers hardness (HV) is calculated using the applied load divided by the surface area of the indentation.
Q2: How to maintain the Vickers hardness tester?
A2: To maintain a Vickers hardness tester, regularly clean the indenter, stage, and lenses with a soft, lint-free cloth to prevent dust buildup. Inspect the indenter for damage or wear and replace it if necessary. Keep the tester in a stable, vibration-free environment with controlled temperature and humidity. Avoid excessive force when handling samples, and cover the instrument when not in use to protect it from dust and contaminants.
Q3: Are there any safety concerns when operating the Vickers hardness tester?
A3: Yes, there are safety concerns when operating a Vickers hardness tester. The main risks involve handling the sharp diamond indenter, which can cause puncture injuries if mishandled. Applying excessive force during testing may damage the specimen or the machine, posing potential hazards. Eye protection is essential when observing the indentation under a microscope to prevent injury from debris or reflections.
Tips: What is the measurement range of this digital Vickers hardness tester?
The digital Vickers hardness tester has a wide measurement range of 5 to 3000 HV, making it suitable for testing materials from very soft metals to extremely hard alloys. It operates by applying a precise load on the material surface through a diamond indenter and measuring the resulting indentation to calculate the Vickers hardness value. This broad range allows for versatile applications across industries, including metals, ceramics, and composites.
