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.
