Strumenti di misura analogici, strumenti di thermotechnics

A bunch of dusty analog measuring instruments in an old thermotechnics laboratory from communism days. The faculty of Transylvania in Brasov. These old instruments still are in a good shape and can provide precise values. They always tell us in the faculty: The old ways are the best ways! Most of the teachers are old but they know how to make students understand every aspect of their lesson and it's impossible not to love the way they teach - devotedness and lots of patience.
