Experimental Digital Thermal conductivity of composite plane wall apparatus

Make -EEI, Model- HT-11, Origin- India

DESCRIPTION

Composite Wall Apparatus offers basic experiments for targeted teaching on the topic of heat conduction through various metals. Heat conduction occurs through the respective sample from top to bottom. Two samples can be inserted into the experimental unit at the same time, in order to investigate thermal conductivity through multi-layered metals. Perfectly matched components ensure rapid heating and trouble-free measurements. The temperature of the metal samples is taken on the top and bottom by means of thermocouples. The microprocessor-based instrumentation is well protected in the housing.
