2.1 HR-150A Motorized Rockwell Hardness Tester

HRM-45 Motorized Superficial Rockwell Hardness Tester

Features: Hardness Testers are based on the same construction principle of the COMP series which are already well, The measuring device consists of a micrometer gauge with standard or superficial scale, allows direct reading of 1 unit and of 0.2 rockwell units.The loads may be selected by means of a knob ergonomically placed on the right side of the instrument.Tests are carried out manually by operator has displayed the correct pre-load application on the dial gauge and set the scale to zero by the dial gauge external ring.

Usage: HR-150A serves to measure the hardness of hardnetals, carburized steels, quenched steels, hardcast irons, mild steels, AI-alloys, Cu-alloys and malleable irons.

HRM-45 serves to determine the superficial rockwell hardness of ardmetals, carburized, nitrided layers and other chemical freating layers, it is also used to for hardness test of thiner pieces.

2.2 HR-150DT, HR-45DT Motorized Rockwell Hardness Tester:

This series of hardness tester with hig measuring accuracy, veliable performance and applicable to wide fields. By adopting the motor driven automatic loading and unloading technique, that thoroughly eliminates human error in those operations.

HR-150DT serves to measure the hardness of hardnetals, carburized steels, quenched steels, hardcast irons, mild steels, AI-alloys, Cu-alloys and malleable irons.

HR-45DT serves to determine the superficial Rockwell Hardness of hardmetals, carburized, nitrided layers, and other chemical freating layers, it is also used to for hardness test of thiner pieces
