Thermophysical Characteristics Measurement Study

The measurement cell uses the 'box method' in steady-state regime: a unidirectional heat flow is established through a sample of the material under test, and measurements are taken after steady state is reached. Educational Objectives: Allows measurement of the characteristics necessary for evaluating heat balances: thermal conductivity, thermal diffusivity, and specific heat in a short time compared to other methods, for one or two samples depending on cell configuration. Can be used in education, research, and industry. Learn about Thermophysical Characteristics Measurement Study specifications for optimal educational outcomes..

An enclosure (heavily insulated) maintained at low temperature (-5°C) by a glycol water cooler fed by a cryostat. One or more boxes, depending on the chosen configuration:

• For thermal conductivity measurement: the box is internally coated on its upper face with a heating film whose heat output is regulated via a rheostat
• For thermal diffusivity measurement: the box is equipped with an incandescent lamp

Specific heat is determined from measurements of thermal conductivity and diffusivity.
