TSTCB Heat Transfer Series General Description

The Heat Transfer Series, "TSTCB", has been designed by EDIBON to study and compare different types of heat transfer on a small scale.

It allows a wide range of heat transfer demonstrations and study the factors affecting and problems associated with different types of heattransfer.

The minimum supply consists of two main elements: Electronic Console for TSTCB (Common for all "TXC/..B" type modules), "TSTCB/EC",and at least one of the required elements described below.

Each heat transfer module can be individually connected to the Electronic Console for TSTCB (Common for all "TXC/..B" type modules)"TSTCB/EC", which provides the necessary electrical supply and instrumentation connections for the study of the different types of heattransfer.
