The present set-up is designed to determine thermal conductivity of insulating materials in the form of slab. It consists of main central heater and ring guard heater, sandwiched between the specimens which is fitted with Cooling plates on either side. Two identical specimens are clamped between heater that ensures unidirectional heat flow through specimen. Cooling water is supplied by laboratory overhead tank at constant head condition by the end user. Temperature transmitters measure temperature at various places. The whole assembly is kept in chamber and insulated by ceramic wool insulation. It has an interfacing unit designed by Engineers along with Labview software. This educational software allows/enables user to log the real time experimental data and tabulate the experimental/sample reading according to the requirement of experiment. User have a control on data logging, printing the stored data and preparing spread sheets in Excel. Flexible graph plotting facility is also available in the software.

•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.
