TMT Temperature Measurement Unit
The Temperature Measurement Unit, "TMT", is a laboratory-scale unit designed to study the different ways in which temperature can be measured.
The Temperature Measurement Unit, "TMT", works as a temperature meter that uses different temperatures measuring devices to compare, check and analyze the temperature and how is the precision for the measure and for the device that the student has used.
This unit is used to study the different types of temperature devices, the temperature phenomenon when the student works with these types of devices (Peltier’s thermoelectric effect and Seebeck’s thermoelectric effect between others) and the difference when the student works with different device disposition (Direct measurement thermocouple, parallel association of thermocouples or series association of thermocouples, between others).
