Thermal Conductivity Of Insulating Slab

Thermal Conductivity Of Insulating Slab

Thermal Conductivity Of Insulating Slab

The set-up is designed to determine thermal conductivity of insulating materials in the form of slab. The apparatus consists of main central heater and ring guard heater, sandwiched between the specimens. Cooling plates are provided on either side of the specimen. Two identical specimens are clamped between heaters that ensure unidirectional heat flow through specimen. The whole assembly is kept in chamber and insulated by ceramic wool insulation around the set-up.
