RM5116 Bell in Jar
For demonstrating the principle that sound waves do
not travel in vacuum. Consisting of a glass bell jar,
with bell mounted on a rubber stopper and electrical terminals.
RM5118 Bourdon Gauge
For the measurement of actual (absolute) gaseous pressure.
This apparatus is a laboratory demonstration version of
the standard Bourdon type of pressure gauge widely used
in industry. The instrument comprises of a circular gauge
having 2 an overall diameter of 100mm. The dial read 0
to 100 lb/in 2 and 0 to 7 Kg/cm . The gauge is carried
upon a circular pillar 19x16mm diameter. A tubing 8mm
diameter projects from the side of the pillar to provide
connection with the system under investigation. The complete
apparatus is provided with a heavy cast iron base.
RM5120 Manometer, U-Tube
Easy to use manometer. Consists of a large U-shaped
tube 50cm high and 2.5cm in diameter. The unit is mounted
on a hardwood support with a metric ruler on both sides.
RM5122 Boyle’s Law
Apparatus
Comprising two glass tubes, one closed at the top
and the other open. Their lower ends are connected together
by 1metre of rubber pressure tubing. Both tubes are
mounted on sliding brackets which may be locked in any
position on the metal supporting rods. The stand, made
of metal, carries a scale graduated from 0 to 100cm
in the center. Supplied without mercury.
