Diagonal Reading - Manual Filler micrometer eyepiece (10 X) with 0.5 Micron accuracy OR Digital measurement with the help of Digital Filler micrometer eyepiece (10 X) with 0.025 Micron accuracy.
Computerised Attachment: With this attachment one can convert manual hardness to computerized one. This has many advantages like higher accuracy as of bigger indentation, operator ease as one can get the Microhardness value by just clicking two diagonals of indentation image on the screens. Further one can get plot of effective case depth graph. All the readings with image and graphs can be stored, printed. This model MVH-II consists of
- 1/2" CCD Camera (High resolution monochrome) with interface adaptor
- Image grabber hardware.
- Dedicated image processing Software for Vickers Hardness number, effective case depth hardness graph. Hardness Conversion facility.

Overload protection, variable test speeds, and digital touch panel controls provide a safe and intuitive user experience, while onsite installation and training support smooth onboarding.
FAQs of Micro Hardeness Testing Machines:
Q: How does the micro hardness testing process work with this machine?
A: The machine uses a diamond indenter to apply variable loads (10g1000g) onto the specimen, creating an indentation. The optical system magnifies the indents at 100x, 400x, or 1000x, allowing precise measurement of hardness values, which are automatically calculated, displayed, and exported for analysis.
Q: What types of specimens and applications are suitable for this equipment?
A: This tester accommodates specimens from 1 mm to 30 mm thick and up to 20 per batch. It is ideal for metallurgical laboratories, material research, and industrial quality controlmeasuring Vickers and Knoop micro hardness on metals, alloys, and advanced materials.
Q: When should auto or manual calibration be used?
A: Auto calibration is recommended for routine operation, ensuring consistent accuracy with minimal intervention. Manual calibration can be performed for verification after maintenance, or when testing uncommon materials, to optimize precision and reliability.
Q: Where can the results from the tests be exported and analyzed?
A: All results are exportable via PC connectivity through USB or RS232 ports. Test data can be saved directly in Excel or CSV formats for further analysis and reporting, integrating easily into laboratory information management systems.
Q: What are the benefits of the overload protection safety feature?
A: Overload protection prevents accidental damage to the indenter, sample, or internal mechanisms by monitoring applied forces and stopping operation if excessive loads are detected. This ensures operator safety and extends equipment lifespan.
Q: How is sample positioning managed during testing?
A: Sample positioning is handled by a motorized XY stage, allowing precise and repeatable movement for each test point. This minimizes human error and optimizes throughput, especially when testing multiple specimens in a batch.
Q: What support and service options are available for this machine?
A: Onsite installation and training are included, ensuring users understand operational procedures, calibration, and software features. Ongoing service support is available from the manufacturer, supplier, and exporter in India.
