• Total Test Force - 1839, 2452N (187.5, 250 kgf)

'FIE' new 'RASN' series of Hardness Testing Machines come with much improved design and look with following major design changes :

• The machine body is having a taper front look and a big size dial gauge in the front. The machine is powder coated for far better look. The paint shade do not fade and machine looks like new over year.
• The elevating screw of machine is guided in a hardened and ground bush, not allowing movement of elevating screw more than 0.05 mm when raised to full height. The accessory is returned for years together due to hardened bush.
• A hardened and ground stepped bush is fixed on top of main screw for location and rest surface. This guarantees no change in results due to rough handling of test table or test piece. It means a trouble free long life machine accuracy.
• An antifriction linear bearing with almost no clearance is provided for a perfect vertical movement of loading plunger with minimum friction. This enable testing of small dia. pin or ball upto 3 mm dia.
• All machine models are provided with automatic zero setting dial gauge or digital readout. Hence zero setting at every test is avoided.
• Our Hardness Tester confirm to respective standard as under. IS : 3804, BS 10109-2 & ASTM E-18 for Rockwell Test.
