Item Description

Sci-tech Linear Conduction Heat Transfer Model TH 035
has been designed for students to study the phenomena of Linear Heat Conduction. The setup consists of a Heating Section, Cooling Section & Specimens of different metals. The specimens can be fitted in between Heating & Cooling section. Test specimens of same metal or different metals can be clamped in between the heating & cooling sections.

Temperature sensors record the surface temperature along length of the specimen. Instruments are provided to measure the Temperatures, Power Input to heater & Cooling Water Flow rate.

Detailed Operation & Maintenance Manual is provided along with the trainer.
