  • Application of nanocrystalline metal oxide gas sensors for air quality monitoring

    Increasing concern regarding health effects caused by air pollution, together with the limited spatial resolution achievable with conventional monitoring stations, have driven efforts to develop inexpensive metal oxide gas sensors for air quality measurements. The sensing mechanism is dependent on physicochemical reactions between adsorbed gas molecules and oxygen species on the oxide surface, ...

  • The ‘ins and outs’ of air quality monitoring

    The National Institute for Health and Care Excellence (NICE) recently issued draft guidance on ‘Air pollution - outdoor air quality and health.’ In the following article Jim Mills, Managing Director of Air Monitors Ltd, explains why there will need to be more funding for monitoring if the mitigation measures mentioned in the guidance are to be implemented effectively. Jim also ...

  • The challenges and benefits of local air quality monitoring

    A new generation of air quality monitors is now being offered to provide localised, real-time air quality readings – but the potential benefit is only just starting to be realised. It is generally accepted that whilst measurements from air quality reference stations are highly accurate, they are not sufficiently location-specific. Key pollutants – such as NO2 and PM2.5 ...

  • Double benefit of monitoring Indoor Air Quality (IAQ)

    It is a difficult balance to save money and energy yet maintain a comfortable and healthy indoor air environment. A logical solution to controlling indoor air pollution is good ventilation coupled with IAQ monitoring using gas sensors. This can ensure healthy indoor air as well as a more efficient HVAC system.  Typical IAQ investigation and examination consists of taking single-point ...

  • Mining Emissions Effectively Monitored with Micro Pulse LiDAR Technology

    Mining operations include blasting, excavating, scraping, and sifting large amounts of dirt. These activities create dust and other emissions that are transported by air currents to surrounding areas. It is easy to say that dangerous particulate matter (PM) generated by mining should be monitored and kept to a minimum; however, it is very challenging to measure the levels of contaminants in the ...

  • Multiple sensor fault detection and isolation of an air quality monitoring network using RBF-NLPCA model

    This paper presents a data-driven method based on non-linear principal component analysis to detect and isolate multiple sensor faults. The RBF-NLPCA model is obtained by combining a principal curve algorithm and two three-layer radial basis function (RBF) networks. The reconstruction approach for multiple sensors is proposed in the non-linear case and successfully applied for multiple sensor ...

  • Monitoring Air Makes Sense

    Did you know that air filters were originally put in air handling systems to protect the life of the equipment, not human life? And that it is not uncommon for air filters to get changed less frequently to save on maintenance costs? Monitoring input from sensors can tell operators when filters and media need changing. We have required food labels that list all ingredients. Why not electronic ...

  • The benefits of monitoring compressed air

    Compressed air is used in many manufacturing processes for many different reasons, from the actuation and control of pneumatic valves and cylinders to the operation of process machinery and tooling. It can also be used as a transport medium for bulk materials or as a purge gas. For all its uses it is nonetheless expensive. This is why, through detailed monitoring, a business can enjoy the ...

  • Top 5 Differences between Micro Pulse LiDAR and Ceilometer Technology

    If you are evaluating backscatter LiDAR sensors for measuring aerosols, cloud vertical structure, and planetary boundary layer (PBL) heights, what factors should you consider in your comparison? It really comes down to a choice between the traditional analog technology used in ceilometers and the more recent advanced technology found in Micro Pulse LiDAR (MPL) sensors. To select the best tool ...

  • Pepsi Is Launching the First Ever “Nitro Soda”

    Nitrogen-infused or nitro beverages have been among the biggest trends in the beverage industry. There's been no shortage of nitro cold brew coffees and nitro beers, but never a nitro soda—until now, with the launch of Nitro Pepsi. The new beverage was sampled at the 2019 Super Bowl and while you won't find it on tap just yet, here's what you can look forward to. Introducing Nitro ...

  • Observational needs for four-dimensional air quality characterization

    Surface-based monitoring programs provide the foundation for associating air pollution and causal effects in human health studies, and they support the development of air quality standards and the preparation of emission reduction strategies. While surface-oriented networks remain a key tool for addressing traditional single pollutant human exposure challenges, these networks in isolation are not ...

  • Designing and Implementing Perimeter Air Monitoring Programs

    Perimeter or fenceline ambient air quality and meteorological monitoring programs have become increasingly valuable at hazardous waste, landfill, dredging, ports, and MGP remediation sites. Air quality monitoring programs protect public health and reduce owner liability ...
