About Vickers Hardness Tester ( VHT-A Series)

Features

MANUAL EYEPIECE :Equipped with 10x Manual Eyepiece to measure the length of diagonal. The hardness value can be displayed directly on LCD screen by entering the indentation diagonal length.

CAMERA PORT :Machine equipped with dual optical channel, one optical channel for 10X eyepiece and another optical channel is for camera by which machine can be upgraded into computerized model. Both optical channel works simultaneously.

ILLUMINATION SYSTEM :Halogen illumination unit gives very clear images and can be also used as a simple microscope. Halogen illumination unit enter stand by mode after a certain period of inactivity which gives it a long service life and low power consumption.

AUTO TURRET MECHANISM :Equipped with auto turret mechanism. Auto turret perform a series of operation and measuring lens automatically comes back to central position after making indentation. The position of the indenter and the objective lens can be automatically switched using keypad.

LCD Screen :80X25mm LCD Screen can visually display the hardness value, conversion hardness, test force and dwell time.

TEST FORCE :Wide range of test force can be selected with external force selection knob. The test force is automatically displayed on the 80X25mm LCD Screen.

EMERGENCY SWITCH :Equipped with emergency stop switch.

Advanced Hardness Testing Technology

The VHT-A Series utilizes a diamond pyramid indenter and selectable loading forces from 10g to 1kg, providing versatile measurement ranges (1-4500 HV) required in demanding research and industrial environments. Its high-magnification optics (100X, 400X) and automatic turret enhance measurement precision, while the variable dwell time allows customization for a diverse range of specimen types.

Intuitive and Efficient Operation

Featuring a user-friendly touchscreen interface, selectable illumination (LED or Halogen), and built-in data storage with export capabilities, the Vickers Hardness Tester facilitates ease of use and streamlined workflow. English and Chinese language support ensures broad accessibility, with the ability to test multiple specimens via the turn-table design.

Reliable and Regulatory Compliant

Designed for reliability, the VHT-A Series is supplied with certified calibration blocks and complies with ISO 6507 and ASTM E384 standards. Its robust, bench-top mounting and consistent accuracy (3%) make it suitable for laboratories, quality control, and industrial material analysis across various sectors in India and beyond.

FAQs of Vickers Hardness Tester ( VHT-A Series):

Q: How does the VHT-A Series Vickers Hardness Tester operate?

A: The VHT-A Series tester works by pressing a diamond pyramid indenter into the sample with a selectable force (from 10g to 1kg). The resulting indentation is examined under 100X or 400X magnification, and the hardness value is calculated digitally, complying with ISO 6507 and ASTM E384 standards.

Q: What materials can be tested using this equipment?

A: This instrument is designed for hardness testing of metals and alloys in various industrial, laboratory, and metallurgical settings. It accommodates standard specimens up to 100 mm and is suitable for measuring a hardness range from 1 to 4500 HV.

Q: When should calibration be performed on the VHT-A tester?

A: Calibration should be carried out before initial use and periodically according to laboratory protocols or regulatory requirements. The instrument is delivered with a certified test block to ensure accurate and traceable results.

Q: Where is data from the hardness tests stored and how can it be exported?

A: Test data is stored internally in the machines memory and can be easily transferred to a PC using RS232 or USB interfaces, allowing for efficient documentation and analysis.

Q: What is the process for selecting the load and dwell time for a test?

A: Users can select the desired load (10g to 1kg) and adjust the dwell time (0 to 60 seconds) directly on the touchscreen interface. This enables tailored testing procedures for various sample types and material properties.

Q: How does the VHT-A benefit laboratories and industrial facilities?

A: Its precise measurement, fast response (<5 seconds), and reliable operation increase efficiency in quality control and research tasks. Features such as automatic turret, integrated camera, and multilingual support make it highly accessible and adaptable in diverse work environments.
