Air monitoring

19 July 2017

Air Monitors has launched three ambient air quality monitoring instruments.

“Highly innovative technology is employed within all three monitors,” managing director Jim Mills said. “For example, the Spectra-1 from PKL Technologies is a robust, portable open-path TDLAS monitor, capable of monitoring a wide range of target gases remotely. In addition, the Model 211 and the Model 405, both from 2B Technologies, employ USEPA Federal Equivalent Methods for the interference-free measurement of Ozone and NO2 respectively.”

Portable and lightweight, the Spectra-1 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 suitable for applications such as landfill, fracking, fenceline monitoring, fugitive emissions, greenhouse gas monitoring and other projects where environmental monitoring is required.

The 2BTech 405 is a direct reading Nitrogen Dioxide analyser. In contrast with chemiluminescence instruments where NO2 must be converted to NO with variable efficiency, the Model 405 measures nitrogen dioxide directly by absorbance at 405 nm. This new absolute method is said to require much less power than traditional techniques and is smaller and lighter too.

The 2BTech 211 measures ozone with a proven UV absorption method and a patented gas-phase titration technology.
