TR 5018PA Tochline

Rockwell automatic hardness tester

The Rockwell hardness tester TR 5018PA is designed to measure the hardness of metals and alloys according to the Rockwell method in accordance with GOST 9013-59, plastics according to GOST 24622-81, graphites and metallographs, plywood, pressed wood and other materials.

PRINCIPLE OF OPERATION: Automatic hardness measurement mode. The hardness scale and the corresponding test load are selected in the menu of the electronic digital block (CB). The preload is set automatically, the test process is shown on the display. Setting the preliminary and main loads, holding and removing loads, displaying the result on the display occurs automatically.
The device is equipped with a high-precision strain gauge. The electromechanical system provides a smooth application of the main load, endurance for a given time and load removal.

Features of the electronic digital unit:
• Work in dialogue mode;
• Hardness scale selection;
• Setting the exposure time under load;
• Recalculation of hardness values, taking into account amendments for convex spherical and cylindrical surfaces in accordance with GOST 9013-59;
• Display of loading process and holding time;
• Sorting into hardness groups LESS, NORMAL, MORE;
• Statistical processing of a series of measurements;
• Saving the results in the memory of CB;
• Auto-tuning (calibration) according to standard measures of hardness;
• Recalculation of hardness values ​​in other scales and methods;
• Touch control;
• Multi-user interface;
• Saving results to a USB flash drive.
The lowest division price (discreteness of the report) of a digital electronic unit, when measuring hardness according to the Rockwell method, is not more than 0.1 units of hardness, which corresponds to a tip movement of 0.0002 mm.
