The history of Spriano begins in 1923, at the very initial stages of development of instrumentation, with 25 employees in Milano downtown. The founder of the company was Guido Spriano, born in Piedmont, fore-runner of the modern self-made man, who had been considering already for many years the production of thermometers and pressure gauges as his chosen industrial activity.
In 1936 Spriano created, first in Italy, the modulating pneumatic controller, bringing a positive technical improvement to the rubber, petrochemical and food industries. During the second world war, Giuseppe Marzorati went into partnership with Guido Spriano bringing competence and experience in the field of trade and organisation, thus giving the programs a long-range scope. Taking advantage of the market recovery, the Company renovated its plans, enlarged the technical office and improved the sales department, creating an agents network.
