Blue Steel Engineers Pvt Ltd offers Precision Metal Hardness Tester. Blue Steel Engineers Pvt Ltd. Has received many international prizes like The German Gold Medal at the Leipzig Spring Fair for "Product Excellence", International Gold Medal at the 35th Plovdiv International Fair [Bulgaria] for "Product Excellence". Precision Metal Hardness Tester is a light weight instrument. The `C` frame body serves as a spring to apply the load. As pressure is applied to the indentor by means of a hand wheel, the `C` frame opens ever so slightly. The movement is transmitted across the frame by means of a lever that actuates the hand on by the indicator dial causing it to rotate. The dial is marked in standard Rockwell loads.
