Excellent apparatus to study the Gas Law. Very easy to study and demonstrate the relationship between the pressure, temperature, and volume of a gas that is constant. The volume of the air can be easily changed by turning the piston and the pressure and themperature can be noted from the gauges. By repeating the process, the law can be confirmed.
The whole unit mounted on a sturdy metal base 6.25inch(160mm) x 4.75inch(120mm) x 1.25inch(30mm).
Total height with piston at the top 11.5inch(290mm).
Piston barrel size 4.25inch(110mm) x 1.25inch(32mm) dia.
Pressure gauge dia. 2"(50mm), reading -1000 to 3000 hPa.
Requires one AA battery for digital thermometer, not supplied.
