Gasmet story begins in 1990, when a Finnish manufacturer of shelters, blast resistant and gastight doors, Finntemet Oy, acquired Scanoptics’ FTIR business. The reason why a shelter manufacturer company was interested in gas analysis was, that since 1959 in Finland, it has been compulsory to include a shelter in any building over a certain size. Naturally, the quality of air inside these shelters became a primary concern. This acquisition led to the creation of Temet Instruments Oy. At that stage, the company consisted of just four scientists.
