HR-150A Rockwell Hardness Tester
HRM-45 Superficial Rockwell Hardness Tester
Introduction
These models hardness Testers are based on the same construction
principle of the COMP series which are already well known for their
economic, reliability and easy using. The measuring device consists of a
micrometer gauge with manual zero setting. The 108mm dial with either
Rockwell standard or superficial scale (150-100-60Kgt) (15-30-45Kgt),
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 operating
the lever on the right side of the instrument, once the operator has
displayed the correct pre-load application on the dial gauge and set the
scale to zero by the dial gauge external ring. By means of a knob on the
lower left side of the instrument, operator can adjust the descent speed of
unloading.
Application
Model HR-150A used to measure the hardness of hard metals, carburized steels, quenched steels, hard cast
irons, mild steels, Al-alloys, Cu-alloys and malleable irons.
Model HRM-45 used to determine the superficial Rockwell hardness of hard metals, carburized layers and
other chemical treating layers, as well as thin metal pieces.
