China Digital Rockwell Hardness Tester

HRS-150 Digital Rockwell Hardness Tester

The HRS-150 Rockwell hardness tester is designed for ease of use and safety in operation and conforms with the international Rockwell standard. Depending on the combination of indenter type and applied total test force, a unique symbol is given to each Rockwell scale. The HRS-150 will automatically show your selection of a specific Rockwell scale on the LCD display, and indicate which load is being used. The integrated autobrake mechanism allows the preliminary test force to be applied manually without the possibility of an error. After application of the preliminary force, the HRS-150 will proceed with a fully automatic test: Loading, dwell time, unloading, and computation of the hardness value on display. Connected to the included printer, by means of an RS-232 output, its possible to print out all results directly.
