To determine co-efficient of expansion of a gas at constant pressure.
A glass U-tube with a bulb and stopcock at one end, the other limb being open.
An outlet tube from the bottom of the U tube passes through a rubber bung and has a stopcock at the end.
The stem below the bulb is graduated 3 x 0.1 ml. An inlet tube with a mohr clip also passes through the bung.
A glass water jacket encloses the U tube.
All glass parts made of borosilicate glass requires only 20 ml mercury, which is not included.
Fitted on a wooden base cast metal uprights and rod mountings.
A 20-0-20 scale is provided to notice the expansion in rods.
The counter weighted needle is used for easy reading.
A knurling screw is provided for zero adjustment.
Supplied with three metal rods one of each Aluminium, Brass and Steel.
Consists of a thick brass calorimeter 90 x 65 mm, a bung with steam inlet and outlet tubes, a felt cover and a one liter brass sheet boiler with bung to take the steam tube.

Sliding indicator on right hand limb with reservoir sliding on vertical clamping rod.
Metal vessel to surround the bulb.
Mounted on wooden stand, height 740 mm.
All glass parts except reservoir are made of borosilicate glass.
To illustrate expansion of metal on heating and contraction on cooling, with steel bar of length 100 x 10 mm and plated brass gauge with a cutout to just accommodate the bar and two holes through which the bar passes when cold.
Double-Wall Calorimeter with 1.5 ohm heating coil and 4 mm standard terminals for electrical connections. Complete with insulated stirrer and single-hole rubber stopper.
