The apparatus is designed to determine thermal conductivity of different liquids. The apparatus consists of a heater. The heater heats a thin layer of liquid. A cooling plate removes heat through liquid layer, ensuring unidirectional heat flow. Temperature is measured across the liquid layer and complete assembly is properly insulated. A proper arrangement for changing the liquids is provided. The whole assembly is kept in a chamber. The present set-up has a facility to interface the system with computer which enables to log the experimental data using computer. The educational software and data-logging package has been developed for unit. The software environment base is of Labview of NATIONAL INSTRUMENTS, USA. This software is compatible to interfacing unit designed by Engineers. This software package provides a comprehensive educational software environment within which the investigations can be performed. This software is capable to tabulate the sample readings according to the requirement of experiment under study and results obtained can be compared. The real time data acquisition can be done by interfacing the set-up with computer using software. Software allows the user to have control on data logging, printing the stored data, preparing spread sheets in Excel etc.

• Valves are provided for drain, charging & overflow line to make system flexible. 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.
