Vickers Hardness Tester is simple & accurate in design.  It is suitable for measuring the hardness of precision metallic parts with wide testing range - from soft to hard & their accurate results are widely acclaimed.  These testers strictly conform to IS "1754 Part I & Part II - 1986

• Wide testing range, from soft metal such as lead, up to the hardest, like hardened steel.
• Tiny indentation allows testing of a precision finished parts.
• Thin sheet metal are perfectly tested.  Because applied load is very small.
• Same Hardness number is obtained on the same specimen, regardless of the load applied.
• Motorized loading and unloading cycle.
• Built-in projection screen to get accurate results.

Construction :
To accommodate the high precision loading system & an optical projection screen the machine frame is designed sturdy.  Specimen is placed on testing table.  The test cycle is fully automatic.  The accurate lode is applied on a diamond penetration by means of a lever & weights.  The load is removed automatically after a specific lapse of time.  The objective is indexed with the test piece & the diamond indentation is projected on the measuring screen.  The diagonals of the indentation can be measured by means of the micrometer screw of the projection screen.

Example : 
Applied objective with 70-fold magnification length of diagonal of indentation 632 micron=0.632 mm.
