SCI-EDU760003
Description:
Computerized Composite Wall Apparatus
Specification:
The Computerized Composite Wall Apparatus offers basic experiments for
targeted teaching on the topic of heat conduction through various
metals.
To this end, one of eleven samples is used.
The upper region of the sample is heated by an electrical heater and the
lower section cooled by a Peltier element.
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.
With explanatory texts and illustrations the educational software
significantly aids the understanding of the theoretical principles.
The microprocessor-based instrumentation is well protected in the
housing.
The software consists of a software for system operation and for data
acquisition and an educational software.
The unit is connected to the PC via USB.
FEATURES:
Calculate the thermal conductivity ? of different metals
