These hardness Testers is 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.
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 HR-45A used to determine the superficial Rockwell hardness of hard metals, carburized layers and other chemical treating layers, as well as thin metal pieces.
