ROCKWELL BRINELL fixed hardness tester NR3 series:
The NR3 hardness tester operates according to the Rockwell principle with preload and standard loads, but it also allows Brinell tests to be carried out with direct reading of the hardness value on the digital display, thus saving a considerable amount of time, without the operator having any influence on the reading of the indentation. The NR3 a hardness tester is a versatile instrument that is very easy to use. Combinations of different loads and standard indenters allow inspection of materials from the hardest to the softest alloys. An RS 232 data output allows results to be printed on a printer. This durometer is robustly built, easy to service and requires no special maintenance.
