From this human and volcanic history, SETNAG was founded in 1986 in Marseille.

In 1993, SETNAG sold its first combustion analyser, the ATK/F-2020 model to PILLARD, a leading burner manufacturer from Marseille.

In 1998, during the exhibition at the Turin Dome, our JC48V trace oxygen analyser was selected to control the atmosphere of the enclosure where the Holy Shroud is kept.

In January 2000, SETNAG obtained the ISO9001 certification which confirms the seriousness and the quality of the work accomplished daily by its team.

Thanks to its expertise in oxygen analysis, SETNAG developed a customised sensor for Environnement SA in 2001. This sensor is integrated in the MIR-FT to correct the pollutant values measured by their Fourier Transform technology analyser.

Two years later, SETNAG signed a contract with Air Liquide to equip their APSAs (nitrogen production plant on customer site).

In 2009, SETNAG moved to its current offices/location in the Marseille Technopole of Château-Gombert (a new district fostering research facilities and high-tech industries).Thus, it doubled its production space.

In September 2016, SETNAG happily celebrated its 30th anniversary.

In May 2017, Michel Gantès retired, and the company was acquired by three of its employees.
