MI.SA-1001 Specific Gravity Frame Also known as Buoyancy Balance
Milestone Instruments
Specific Gravity Test
A mechanical lifting device is used to raise the water tank through the frame height immersing the specimen suspended below the balance. The balance supplied calculates the specific gravity of the sample automatically.

It consists of one frame having the arrangement for lifting the water bucket and has one digital scale (Capacity 15 Kg accuracy 1gm) on the top of frame having the arrangement of hooking the density basket of size 20 cm height and 20 cm dia
Meets :-EN 12390-7, 1097-6

MI.SA-1001001 Density Basket for Specific Gravity
Fabricated with M steel size 20 cm height and 20 cm dia

MI.SA-1005 Los Angeles Abrasion Testing Machine
Milestone Instruments
Los Angles Abrasion Testing
This machine is for determining the resistance to wear of small size coarse aggregates and crushed rock. The machine consists of a hollow cylinder, mounted on a sturdy frame on ball bearings. A detachable shelf which extends throughout the inside length of the drum catches the abrasive charge and does not allow it to fall on the cover. The drum is rotated at a speed of 30-33 rpm by an electric motor through a heavy-duty reduction gear. Motor is suitable for operation on 220 V, 1 phase, 50 Hz, AC Supply. Supplied complete, with a tray for collection of the material, and abrasive charge
Meets :- IS: 2386 (Part 4), BS: 812, ASTM C- 131, AASHO T96
