The Model HRS-150 digital Rockwell Hardness tester is an organic whole of mechanical and electrical hardness testing instrument, with its novel appearance, directly observed digital display device and micro-computer control lifting and lowering screwed and automatic feedback lock among rotary wheels, connecting outside to the printer, full realizes the automatic. That completely eliminates error in those operations and reading. It can used to measure the Rockwell hardness of ferrous, non-ferrous metals and plastic materials.
