New Open-path Air Quality Monitor

Air Monitors (Tewkesbury) has announced the launch of a new open-path laser gas analyser for industrial and environmental monitoring applications. The Spectra-1 from PKL Technologies is a robust, portable TDLAS monitor, capable of monitoring a wide range of target gases remotely.

Employing proprietary hardware and software the Spectra-1 is housed in an enclosure selected for its resistance to extreme shock and vibration. Portable and lightweight, it can be easily transported from site to site, or left in place as a continuous monitor. The tuneable laser can be set to measure a specific gas from a range of options including HF, CH4, NH3, CO2, CO, HCN, C2H2, C2H4, C2H6, H2S and others. Consequently, this instrument is ideal for applications such as landfill, fracking, fenceline monitoring, fugitive emissions, greenhouse gas monitoring and other projects where environmental monitoring is required.

As an open-path monitor, the Spectra-1 measures the total amount of the chosen gas in the path between the laser source and the reflector (ppm-m). This can be converted to ppm by dividing by the path length to derive a path-average concentration. Shorter optical paths may be chosen to determine the distribution of the monitored gas species.

Summarising, Air Monitors Managing Director Jim Mills says: “The Spectra-1 is a very useful addition to our product range because of its portability and flexibility in the choice of measurement gas. As a result, we believe that this will be popular with industrial users looking to detect fugitive emissions, and with environmental consultants that need to be able to monitor sites for a specific time period.”
