PLUMMET BALANCE/ LOAD FRAMES

Plummet Balance
Ref. Standard  : IS:2720 (Part 4)
EKE 057:

Features
•    Simple Operation
•    Sinking of Plummet to right depth is all that is required before taking a reading
•    Grain Size distribution curve for the entire range of particles size is possible. which is not with pipette method where only specific sizes of particles can be determined
•    Eliminates computation involved Hydrometer Method
•    Percentage of soil in suspension can be can be directly read
•    Grain Size distribution curve can be directly plotted as experiment progress

The  Plummet Balance consists of a vertical rod mounted on a heavy base with leveling screws. A light weight pointer with pointed steel pivots, turning in jeweled bearings moves over a scale graduated in parentage units 0-100 in 2% divisions. The balance moves up and down over the vertical rod with the help of rack and pinion arrangement. A chart showing the relationship between K and Temp. of suspension of soils of varying specific gravity from 2.4 to 2.8 to help solve stokes equation is provided . Supplied complete with one Perspex plummet , one measuring jar, one rider weight for zero adjustment and one rider weight for adjusting the pointer to 100%
