Features :Testing range is very wide, from soft metal such as lead,upto the hardest, like hard steel.Same hardness number is obtained on the same specimen,regardless of the load applied.The indication is tiny and allows testing of a precisionfinished part.Loading and unloading cycle is motorized.Thin sheet metal is perfectly tested because the loadapplied very small.Built-in projection screen to get accurate results.
Digital Vickers Hardness Tester is a simple and accurate means to produce and automatically measure the diamond indentation to give micro hardness numbers directly. These testers are suitable for measuring the hardness of precision metallic parts with wide testing range - from soft to hard, and their accurate results are widely acclaimed.
Construction : The machine frame is designed to accommodate the high precision loading system. Specimen is clamped by vice or supported by proper fixtures. The test cycle is fully automatic. The accurate load is applied on a diamond indentor by means of dead weights. After a lapse of time, the load is removed automatically. The image id digitallized using a CCD Camera fitted on the machine and is captured by the PC. The diagonals of the indentation are measured by the PC and the Micro Hardness number is displayed directly on monitor.
