Micro Vickers and Knoop Hardness Tester – Digital and CCD Models

The first product is the NG-1000 Series Micro Vickers and Knoop Hardness Testers, which are designed for precision and ease of use, providing an array of options to meet the diverse needs of industries focused on material testing. These testers are available in multiple configurations, from standard digital systems to advanced systems with CCD Optical Analysis Software, which allows users to obtain accurate and efficient measurements of hardness for a broad range of applications.

NG-1000 Series Models

1. NG-1000AGEN: The Standard Digital Micro Vickers and Knoop Hardness Tester. Measurements are made through the eyepiece, and the user manually enters the data into the system using a keypad to generate hardness readings on the LCD display. This model is ideal for users seeking a basic, reliable digital hardness tester for micro applications.

2. NG-1000DGEN: A Digital Micro Vickers and Knoop Hardness Tester equipped with an encoder. The system transmits measurements from the eyepiece directly into the system, significantly reducing manual entry errors and speeding up the measurement process.

3. NG-1000CCD: This advanced model incorporates a CCD camera and analytical software for automated optical analysis. It provides the highest level of accuracy by using the CCD camera to measure indentation images and generate hardness values through the software. The NG-1000CCD is perfect for quality control laboratories requiring precision and automation.

4. NG-1000CCD SEMI: Similar to the NG-1000CCD but with an upgraded motorized XY stage, this model enables semi-automated operation. The user can manually focus on the sample, while the software handles boundary scans and automatic indentation plotting, allowing it to be used for more extensive hardness testing.

5. NG-1000CCD FA: This fully automatic model offers complete automation, including Z-axis control for automatic focusing. Once the path is set, the system performs the entire testing process—from indentation to measurement and reporting—at the click of a button. The NG-1000CCD FA is the most advanced option in the series, suitable for high-throughput environments where speed and precision are critical.

Key Features of the NG-1000 Series

• Testing Forces: The NG-1000 series provides eight testing force options ranging from 10g to 1000g, allowing a broad range of applications from microhardness to slightly heavier loads.

• Vickers Scales: These machines work with scales such as HV0.01, HV0.025, HV0.05, HV0.1, HV0.2, HV0.3, HV0.5, HV1, and HV2 (optional), enabling testing for both soft and hard materials.

• Measurement Conversion: The system supports conversion from Vickers values to HRA, HRC, HR15N, HR30N, HR45N, HB, thus enabling it to be used with multiple hardness measurement scales.

• Precision and Automation: With a minimum measuring unit of 0.01 μm and a Vickers value range of 1HV to 4000HV, the NG-1000 series is built for precision. The motorized turret in all models allows for easy switching between objective lenses and indenter positions, while the loading and unloading of testing forces is fully automated.

• Optical Features: The 10x and 40x objectives provide 100x magnification for observation and 400x magnification for measurements, with the option to extend to 150x or 600x. For models equipped with the CCD, the optical cross rails ensure high accuracy in guiding measurements, and the system’s dual optical path (eyepiece and CCD camera) allows both paths to function simultaneously without switching.

• Software Integration: The VickSoft Software that comes with CCD models allows users to categorize results by part numbers/IDs, convert hardness values into different scales, and generate customized testing reports. Users can also plot hardness curves, store data, and retrieve images for future analysis.
