• The Dual discussion Co-axial Research Binocular Microscope permits simultaneously viewing.
• The same image and provide a facility of discussing about the specimens. It assure comfort for both observers, because all four eye pieces are at the same height.
• It also helps in the training of new staff or students and make discussions easier. It save your lots of valuable time.
• Co-Axial Coarse and fine focusing knobs, provide the highest Degree of working convenience the coarse adjustment has a built in controls to increase and decrease the tension of the focusing knob simply by rotating the adjustment ring. The mechanism is free from Back Lash Fine Motion 0-180.
• The fine adjustment works over the entire coarse focusing range, allowing quick, accurate focusing at any position.

Microhardness testing applied in areas including metallography, precision mechanics, electroplating, material testing and material science. In order to determine microhardness, different shaped indents are pressed into flat material samples with a defined force. Three methods available are :

BRINELL HARDNESS

In Brinell hardness test, an indentation hardness test in which a hardmetal ball is forced into the surface of a test piece, mean diameter of the indentation is left on the surface after removal of the test force is measured.

The Brinell hardness HBW is obtained by software.

The Vickers hardness test, measure length of the diagonals of indentation left in the surface in which a Square-based diamond pyramid, having an angle of 136 degree between the opposite faces at the vertex, is forced. The Vickers hardness is obtained by dividing the test force by the area of the sloping faces of the indentation. The Vickers hardness HV is displayed by software.

The Knoop hardness test is an indentation hardness test in which a rhombic-based diamond pyramid, having an included longitudinal edge angle of 172.5 degree and an included transverse edge angle of 130 degree, is forced into the surface of a test piece. The length of the long diagonal of the indentation left in the surface after removal of the test force. The Knoop hardness HK is calculated by software.
