TVM 5215A Tochline

The micro-Vickers hardness tester TV 5215A is a stationary measuring instrument consisting of a load application system and a measuring unit.
The principle of operation of the hardness tester is based on the static indentation of the diamond pyramidal tip with subsequent measurement of the lengths of the diagonals of the reconstructed print.
The device has a large touch screen, an electromechanical drive to set loads, an integrated optical system, and an automatic rotary turret.
When measured according to the Vickers method, the system for applying the load of devices provides the application of loads of 0.098; 0, 245; 0.49; 0.98; 1.96; 2.94; 4.9; 9.8; 19.6N
The design of the hardness tester is reliably protected from unauthorized access, adjustment of factory settings and software.
Special software for the built-in microprocessor of the hardness tester software is used to enter the initial parameters and start the load application cycle, record, store and statistically process the measurement results and display them on the digital liquid crystal display.

Features of the electronic digital unit:
• Interactive work;
• Hardness scale selection;
• Setting the exposure time under load;
• Display of loading process and holding time;
• Sorting into hardness groups LESS, NORMAL, MORE;
• Statistical processing of a series of measurements;
• Saving results in the memory of CB;
• Auto-tuning (calibration) according to standard measures of hardness;
• Conversion of hardness values ​​to other scales and methods;
• Touch control;
• Multi-user interface;
• Saving Results to a USB Flash Drive.
• Semi-automatic optical system for measuring the size of the print according to the Vickers method with automatic data transfer and obtaining hardness on the display.
