It is intended for measurement of the print formed on a metal surface at determination of hardness by Brinell's method.
Principle of action:
The principle of work of a microscope is based on determination of the size of the print received from cave-in of a ball in the studied material. Counting is conducted on a scale of the grid applied on a microscope lens.
During the work with a microscope lenses with the 2nd and 4-fold increase can be used.
Max. diameter of the measured print: with a lens 4x - 3,5mm, / with a lens 2x - 7 mm;
Division price: 4kh - 0,02+-0,0025 mm / 2kh - 0,04+-0,005 mm;
Field of vision, not less: 4kh - 4,5 mm / 2kh - 9,0 mm;
Increase: 4kh - 50+-2,5 крат / 2kh - 25+-1,2 krat;
Limits of installation of an eyepiece +-4 dptr.;
Dead course of an adjusting ring, no more than 1,2 mm;
Lateral shift of an aiming point, no more than 0,04 mm;
Limit of an admissible absolute error, no more than 0,02 mm;
