Sand Pouring Cylinder Apparatus
This Apparatus is used for determination of the dry
density of compact, fine, medium grained soils and for layers not exceeding
50 cm thickness. A circular hole is dug into the ground, all the soil from
within it collected, weighed and dried, and the hole back-filled with a
standard uniform sand or fine gravel, poured from a calibrated container for
calculating the volume of hole.

The pore pressure measuring apparatus consists of a
screw pressure pump, null indicator in Perspex, pressure gauge, mercury
manometer, volume change burette and the necessary connecting tubes and
valves. It is used for measuring pore water pressure and pore air pressure
in soils. It has many features, which simplify the operation. The Null
Indicator is made from a transparent Perspex block. It is a simplified
U-Tube Null Indicator, in which water can bypass mercury if null indicator
is tilted; thus de-airing process by circulation of water is facilitated.
All features enable a visual check to be made during the de-airing operation
of apparatus. A mercury manometer and a pressure gauge of Bourdon Tube type
are provided on the panel on which the whole equipment is mounted. Very
small positive or negative pressures are observed on the manometer. A 50 ml
burette is clamped to a sliding bracket on one side of the panel. It is used
for measuring the volume change in the specimen when subjected to confining
pressure in the triaxial cell

Sensitive Volume Change Gauge
The Volume Change Gauge illustrated works on the
principle of reversing the direction of flow when the limit of the volume
change scale is reached. The number of cycles with the volume of fluid
handled in each cycle provides the total volume change, whereas the
sensitivity is governed by the dia of the polythene tube used.
The sensitive volume change gauge has realized sensitivity of 0.003 ml/mm
with the 6 ml volume of fluid per cycle. The apparatus consists of a volume
measuring polythene tube running along both sides of a scale and connected
at both ends to two mercury traps. These traps are connected to flow
reversal valves through a manifold. The length of the polythene tube is
enough to measure 6 ml volume of fluid per cycle. A small pallet of mercury
is introduced in the circuit to be used as a cursor, and the movement of
pallet is measured. The unit is tested to a pressure of 20bar (20 kg/cm2)
and is designed for wall mounting.

Sieve Shaker (Gyratory Type)
Carries up to 7 sieves of 20cm diameter. The shaker
is drive by a ¼ H.P. electric motor through a reduction gear. The sieve
table does not rotate but it is inclined from the vertical axis and the
direction changes progressively in the clockwise direction. By removal of a
stop-pin fixed below the table, the shaker can have a rotary motion. In
addition to the gyratory motion of the table, there is an upward and
downward movement ensuring that each square cm of the sieve is utilized. The
whole gear mechanism runs in an oil bath.
Suitable for operation on 230 volts, 50 cycles, single phase, A.C. supply.
Supplied without sieves.

Infra-Red Moisture Meter
It is specially useful for determination of moisture
in substance, that quickly reabsorbs moisture after drying. The infrared
radiation is controlled by a voltage regulator and thereby provides
excellent heat control. The instrument is provided with an indicator lamp.
The torsion balance has a built-in magnetic damper to reduce pan vibrations
enabling quicker weighing. The balance scale (drum) is divided in terms of
moisture percentages on wet weight basis, which are read directly from it.
Graduations are from 0 to 100% in 0.2 % divisions, but readings may be
estimated to 0.1 % moisture content. It works on 230 V, 50 Hz, Single phase,

Speedy Moisture Meter
Using a speedy moisture meter, the moisture content
of soils, sand and other fine-grained material can be obtained quickly with
reasonable accuracy. The test technique is based on the fact that water will
react with calcium carbide to form acetylene gas and the quantity of gas
formed is directly proportional to the water present, leaving a surplus of
the chemical used in the test. The quantity of acetylene gas produced is
indicated on a built-in pressure gauge, which is calibrated in percentage of
moisture on wet weight basis.
