Gas spectroscopy has long roots in NEO. Continuously, new application areas are being explored. Today we are also working in projects related to spectroscopic analysis of fluids.


NEO has provided gas monitors based on spectroscopic techniques for industrial applications since 1990, when the first Open Path Monitors for measurement of Hydrogen Fluoride (HF) were installed in an aluminium potroom in Norway. Following this successful development NEO has been a pioneer in developing gas monitoring instruments based on spectroscopic techniques utilizing the unique spectral properties of tuneable diode lasers. This work has resulted in a completely new and unique range of gas monitoring instruments for a number of applications in industrial process and emission control. The single mode ( i.e. single frequency) characteristics of the diode laser makes it possible to measure the absorption of a particular gas using only one single absorption line, thus avoiding effectively the interference from other gases in the same gas volume, resulting in a highly accurate instrument capable of measuring very low concentration levels when required.

LaserGas Monitors

The LaserGas products, produced and marketed by NEO Monitors provide solutions to many measurement problems where traditional spectroscopic techniques are inadequate, and they have proved to be very competitive, both with respect to performance, reliability and cost. LaserGas instruments have been in use by the industry since 1995 and they are marketed on the international market through reputable distributors working directly with the end customers with installation and commissioning as well as after sales services including calibration and preventative maintenance.

NEO Monitors was sold to Swedish Nederman Holding AB in 2017. NEO retains technology, IPR and competence for continuing the development of gas spectroscopy in other applications. Today, MAP (Modified Atmosphere Packaging) applications and medical applications are the main focus areas, along with spectroscopy for gases in fluids.
