NR3 D/SR, duromètre ROCKWELL Superficiel avec accessoires
Échelle supplémentaire pour NR3

Also known as SUPER ROCKWELL. The NR3 D/SR hardness tester operates according to the Rockwell principle with preload and standard loads, but it can also perform Brinell tests with direct reading of the hardness value on the digital display, thus saving considerable 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.
