HST-HBRV250STEW Universal Hardness Tester
1. Features
Model HST-HBRV250STE is used electronic loading control instead of weight load control, equipped with a newly-designed large displaying screen with good reliability, excellent operation and easy watching, thus it is a high-tech product combining the optic, mechanic and electric features.
It has Brinell, Rockwell and Vickers three test modes and test forces from 3kg to 250kg, which can test several kinds of hardness.
Test force loading, dwell, unload adopts automatic shifting for easy and fast operation. It can show and set the present scale, test force, test indenter, dwell time and hardness conversion;
The main function is as follows: Selection of Brinell, Rockwell and Vickers three test modes; Conversion scales of different kinds of hardness; Test results can be saved for checking or be printed out, automatic calculation of maximum, minimum and average value; can connect to the computer.
2. Application Range
Suitable for hardened and surface hardened steel, hard alloy steel, casting parts, non-ferrous metals, various kinds of hardening and tempering steel and tempered steel, carburized steel sheet, soft metals, surface heat treating and chemical treating materials etc.
