"Faster, Better, Newer" - The Latest Optical and Remote Sensing Technology

Since the start of the Company in 1983, UK company Enviro Technology (ET) has always pioneered new monitoring technology and today, as then, continues to bring innovative new technology to market. Managing Director Duncan Mounsor, a long-time advocate of optical and remote sensing technology uses three words that sum up the newest crop of products available from ET; “Faster, Better, Newer”.Faster

Duncan explains; “the last few years have seen an explosion in the number of laser based optical instruments for the measurement of both gases and particulates sharing similar benefits, namely the speed, accuracy and precision in which they measure and in many cases, improving on older technologies still commonly in use today”.

Take for example the Teledyne-API T500U CAPS direct reading NO2 analyser and the LGR Ultraportable Greenhouse Gas Analyser (UGGA). The T500U measures ambient and trace concentrations of NO2 in air directly rather than by indirect calculation common with older traditional NOx analysers. It is faster, more precise, less complicated and uses 75% less energy too resulting in lower maintenance and running costs and most importantly, better NO2 measurements. The T500U is also MCERTS approved as an additional benefit.

The LGR UGGA measures methane, CO2 and water vapour simultaneously in a small, rugged field portable package. Unlike more traditional FID/GC methane instruments, the UGGA does not require a fuel gas such as hydrogen, which in itself is major improvement in terms of reliability and ease of operation. These benefits, as well as measurement rates as fast as 1 Hz and sub-ppb precision make the UGGA without doubt, one of the most advanced methane instruments currently available and perfect for ecological, atmospheric science and industrial applications.

Moving on to aerosols and particulate matter, whether we need to observe and track aerosols and dust clouds up to 25 km high in the troposphere, measure multiple PM size fractions in real-time on the ground and even quantify multiple heavy metals in air on a real-time basis, ET has the technology to help us understand our environment in faster, newer and better ways.

Duncan concludes; “in my almost three decades in the air pollution monitoring industry I don’t think we have ever seen so much innovation and measurement performance improvements as we are seeing right now. To coin an old phrase “to measure is to know” and it is important that we use the very best measurement tools that are available to us, this is after all how science progresses”.
