The H112 Heat Transfer Service Unit is a fully instrumented, bench-mounted system designed for practical experimentation and demonstration of heat transfer phenomena in undergraduate engineering laboratory. It has regulated and adjustable AC power and is fully equipped with various optional modules and instrumentation for study of heat transfer phenomena such as conduction, convection, radiation, thermodynamic properties of gas-liquid system and heat engines.
The H112C heat transfer unit features digital displays for temperature, voltage, and current measurements, and can accommodate up to 12 type K thermocouples. An optional computer upgrade (HC112) allows for data acquisition and enhanced analysis.
