3B Scientific Thermal Expansion Apparatus - 1mm Measuring Range, 0.05mm Accuracy | Physics Lab Equipment for Classroom Demonstrations & Science Experiments

A device for measuring the thermal expansion of solids in dependence on length and material. The scope of delivery includes three sample tubes (steel, brass and glass) which are heated by passing water vapour through them. Consists of a base strip with a fixed bearing, pilot bearing, pointer and projectable scale. Scale measures 140 by 200mm square approximately. Measuring range: 1mm. Reading accuracy: 0.05mm. 650mm Tube length Approximately.
