Gassonic A/S (formerly known as Innova Gassonic) is the world's leading manufacturer of fixed ultrasonic gas leak detectors. Gassonic A/S was the first company to develop an ultrasonic gas leak detector, and our experience with installations of detectors in the oil/gas and petrochemical industries dates back more than ten years. To ensure full client satisfaction and optimal installation of ultrasonic gas leak detectors, Gassonic A/S offers both products and consulting services/support. The company has a worldwide distributor network consisting of companies with extensive experience within instrumentation and fire & gas.

Gassonic A/S is today part of the General Monitors family of companies. The company was formerly part of the gas division of Bruel and Kjaer and later on Innova AirTech Systems A/S (now Lumasense). Underneath you can read more about the history of the company.

Gassonic A/S is ISO9001-2000 certified.

Ultrasonic gas leak detectors have been marketed for more than a decade now but the technology was actually used even before then.

Mid 1980's: The Dutch gas producer and operator NAM (Nederlandse Aardolie Maatschappij), which is partly owned by Shell, work together with Danish instrument manufacturer Brüel&Kjaer to develop a special designed gas leak detector to use at their onshore facilities in Holland. This leads to the introduction of the first ultrasonic gas leak detector named "WBO989".

1996: Innova AirTech Instruments in Denmark acquires the gas division of Brüel&Kjaer. The ultrasonic gas leak detector, which at this time is still a somewhat simple, yet stable, detector, is made part of the package.

1998: Innova develops a new ultrasonic gas leak detector today called "Gassonic MM0100". In the next years, the detector is installed in the North Sea, mainland Europe, Middle East, America and Africa.

2003: Gassonic is formed as an independent part of the Innova Group in Denmark. At the same time Gassonic introduces onsite services and consulting on how to install the ultrasonic detectors and commission the ultrasonic detection system. Installations now also include the Far East and the Caspian Region.

2005: Gassonic markets the next generation of ultrasonic gas leak detection. The patent pending detector is named "Gassonic Observer". Within the first year, the detector is being installed in the North Sea, Australia, the USA, Indonesia, the UAE, and Germany. Technically a lot has happened over the years to make the ultrasonic gas leak detector an even more reliable and suitable instrument for applications within the oil/gas and processing industries.

2006: Gassonic A/S becomes an independent company.

2007: Gassonic launches new ultrasonic gas leak detector, The Gassonic Surveyor. The detector is ATEX and IEC Ex certified. The development emphasises our dedication to new research and development and our desire to fulfill our clients' needs.

2007: Gassonic A/S becomes member of the General Monitors Family of Companies.
