This paper shows the process of designing and building a thermal test chamber in the thermoelectric tests laboratory at the Universidad Distrital Francisco José de Caldas, Facultad Tecnológica, which allows to carry out standardized testing to different electrical equipment and develop research projects. Throughout the project implementation, the construction and camera control was performed. An air feedback mechanism is equipped in order to make an efficient heating system, likewise the system was established, this one has a PID control (proportional, integral, derivative), which assure the user that the temperature set in the center of the chamber is stable in the shortest time possible.
