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. Two identical specimens are clamped between heater that ensures unidirectional heat flow through specimen. Cooling plates are provided on either side of the specimen. Cooling water is supplied by laboratory overhead tank at constant head condition by the end user. Temperature sensors are mounted on various places and are displayed by a Digital Temperature Indicator. The whole assembly is kept in chamber and insulated by ceramic wool. A Digital Temperature Control facility is provided to have a smooth control on desired temperature conditions as per end user requirements. This control facilitates end user to control required heat input to the heaters,automatically, and further steady state of experiment is achieved in very less time as compared to manual control. Electronic energy meter will be provided to measure the heat input.

•MS Cabinet to accommodate the slab assembly.

•An ENGLISH instruction manual consisting of experimental procedures, block diagram etc. will be provided along with the Apparatus.

•The whole set-up is well designed and arranged on a rigid structure painted with industrial PU Paint.

Experimentation/Learning Objectives
