Our hydrogen sulphide (H2S) monitoring journey literally started in the sludge lanes of a UK wastewater treatment plant in 2017. Since then, AQMesh has been used effectively in a range of applications.

If you are responsible for air pollution around an oil, gas or industrial site, you have a range of options at different price points. AQMesh offers a cost-effective way to continuously monitor ambient air quality, as frequently as every minute, with readings accessed securely online and user-settable alerts.

AQMesh is now able to offer CO2 and H2S within its range of gas options for local air pollution monitoring. The NDIR CO2 sensor, which can be offered within a single AQMesh pod alongside five other gases out of NO, NO2, O3, CO, SO2 or H2S, as well as PM1, PM2.5, PM10, temperature, pressure and humidity, has been developed to deliver a higher performance than those typically used for indoor air quality monitoring.

AQMesh has been used extensively in and around data centres for two main reasons: obligation to monitor emissions from back-up generators and the risk to copper components from hydrogen sulphide.

Five AQMesh pods are currently installed around Keflavic airport in Iceland to monitor gases produced by the nearby volcano at Fagradalsfjall, including hydrogen sulphide (H2S), sulphur dioxide (SO2) and nitrogen dioxide (NO2).

Did you know that we have always been part of wider group of companies, offering a portfolio of emissions, leak detection and gas stream monitoring products, software and services, specialising in methane?

The AQMesh small sensor air quality monitoring system already offers flexibility of monitoring location – through independent power and communications – as well as high data quality and traceability.

AQMesh will be exhibiting at the Air Quality & Emissions show in Telford on 12^th & 13^th October 2022, which this year is running as a live and virtual event. Focussing on air quality and emissions monitoring services, technology and instrumentation, the show offers a variety of industry experts all under one roof, including AQMesh at stand D10.

There is a major trend towards industrial operators including oil and gas, petrochemicals, construction, mining and transport – rail and ports, as well as roads – wanting to look closely at air pollution on and around their sites.

Recent co-location comparison trials against certified reference equipment continue to prove AQMesh performance and reliability for localised air quality monitoring.

AQMesh is currently being used in a number of air quality monitoring initiatives by a range of users. Across the UK, for which today is its annual Clean Air Day campaign, there are a number of pods deployed outside schools, being used by ambulance services, installed at metal foundries and at railway stations.

AQMesh has been long established as the most proven small sensor system for the air quality monitoring market. With an ever-increasing suite of measurement options and proven performance in the harshest environments, AQMesh is ideal for industrial applications.

AQMesh has been measuring ozone (O3) using small sensors since 2011 and the readings from the latest generation electrochemical sensor, using AQMesh v4.2.3 processing, as compared to co-located certified reference readings, consistently show an R2 of over 0.9 with an accuracy ±10ppb (20µg/m3).

The results of the 2019 AIRLAB Microsensors Challenge* were revealed in Paris on 21^st January and AQMesh was awarded the highest score for accuracy of all products presented for monitoring of outdoor air quality.

2022 has seen AQMesh taken up as a proven and flexible air quality monitoring system by more users, including several in mining and construction. New users include mining operators in the Middle East and Africa, and construction companies in Italy, UK and Canada.

A wide range of industrial operators, including mining, construction, ports, landfill and the oil and gas industry, are looking more closely at the air quality on and around their operational sites. This is increasingly driven by legislation, Environmental, Social and Governance (ESG) ambitions, to establish a baseline, or to understand and manage potential pollution sources.

Data collected as part of the UKRI SPF Clean Air Program has proven that AQMesh out-of-the-box performance for PM2.5 exceeds new US EPA targets, with excellent results for PM1 and PM10 as well.

Cleves School in Weybridge, Surrey (UK) has used AQMesh to measure pollution at the primary school’s entrance.

2023 is set to be a big year for AQMesh’s monitoring of particulate matter, with developments in both hardware and data processing offering improved accuracy across key PM fractions.

Generally, the limiting factor will be budget. The clue is in the name with hyperlocal air quality monitoring, and pollution levels can vary hugely over short distances. NO measurements around streets, for example, are often significantly different from one side of the road to the other, particularly if there isn’t much wind and/or a street canyon effect.

We are often asked by customers whether AQMesh can operate in cold conditions. Long-term use at temperatures well below freezing, with ice and snowfall, is indeed challenging. Cold weather operation has been key to AQMesh – improved upon and proven in the field – for over 10 years. The main features, described below, have been most recently been put to the test in Iceland.

Technology is critical to so many essential services during the current global COVID-19 crisis, but it is also allowing local air quality to continue to be monitored, in real-time, across the world. Small sensor air quality monitors such as AQMesh pods can use cloud data storage to ensure that air quality information is stored and accessible even when staff are not able to visit equipment.

Whilst not the only AQMesh pods still in regular use since the product was commercially launched in 2013, two AQMesh pods are still in use in Spain and demonstrate the long life of this small sensor air quality monitoring system.

2022 marked 10 years of innovation and leadership from AQMesh. To highlight the team’s experience, ongoing forward-thinking and its commitment to pushing the capabilities of small sensor systems, here are the top 10 things AQMesh developed first and refined since it commercially launched in 2012.
