In this paper a new test room for thermofluidynamic measurements is presented. The tests have been realised in the Officine Volta (Italy) workrooms as result of a collaboration between researchers of the Department of Fisica Tecnica University of Rome La Sapienza and researchers of the Officine Volta society. The laboratory was thought exploiting the knowledge in the field of thermofluidynamic achieved by the department of Fisica Tecnica in the last few years. The aim was to create a laboratory flexible to the different configurations, providing it with measurement instrumentations that can satisfy a qualitative functional check and a scientific research. The first measurements made on some of the most common diffusers used in the Italian market have given good results and proved the excellent functionality of the laboratory.
