Model SRRH-150A Digital Rockwell Hardness Tester

Hardness Testers are based on the same construction principle of the COMP series which are already well known for their economy, reliability and ease of use. The measuring device consists of a micrometer gauge with manual zero setting. The108mm 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 the operator can adjust the descent speed of the load applied.
