Vickers Hardness Testing Machine
'BIE' makes Vickers Hardness Testers Model BV-250, BV-250-S, BV-120,
BV-120-S, BV-50, BV-50-S, which are suitable for Vickers and Brinell Hardness
of steel and other metals. These machines are designed and manufactured
for very high accuracy, reliability and ease of operation. The
selection of load is affected with the push button control system. The
measurements of diagonal / diameter of indentation is done with the
help of built-in optical system with graduated readout with Micrometer.
After taking indentation on the work piece, the objective lens is
automatically swiveled into position and image of indentation appears
on the focusing screen fitted in front on the machine. A push button is
provided for starting the loading cycle, and unloading is accomplished
through hand lever. This Machine conforms to IS 1754 - 1986 for Vickers
and IS 2281 - 1983, BS-240 for Brinell Test.

Salient Features
- Testing range is very wide, from soft metal such as lead up to the hardest, like hardened steel
- Thin sheet metal is perfectly tested because the load applied is very small
- Same hardness number is obtained on the same specimen, regardless of the load applied
- Built in projection screen to get accurate results.
