Description

The TK-2M device in accordance with GOST 13407-67 is intended for measurement of hardness of metals and alloys by Rockwell's method according to state standard specification 9013-59.

The hardness gage provides grading of products on groups of hardness by means of indications of the arrow indicator according to indexes. In quality an indentorah steel balls by diameter (2,5 ±0,0025) (5±0,004) (10±0,004) mm in accordance with GOST 3722-81 with a hardness of not less HV 850, degree of accuracy 20 are used.
