Low cost air quality monitors for

Environment, Social and Governance (ESG) requirements and new UK targets for PM2.5 make fence-line monitoring an essential tool for construction, mining and incineration (among others). 
You need a low-cost, reliable monitor for one or two target pollutants. The smaller, simpler and more power efficient it is, the better. 


  • 1 PM + 1 gas sensor

  • Low energy usage

  • Lightweight & compact

  • Remote diagnostics

    Our award-winning Praxis/Cube is as accurate and low-maintenance as its larger brother, the Praxis/Urban, while offering cost savings due to its small format.

    Real-time monitoring and a high sampling rate supports you to distinguish on-site pollutants from background pollutants. 

    Praxis monitors use independently validated error correction methods, so you get exactly what you need for compliance purposes without needing to waste resources checking or post-processing your data.

    All you need do is install and switch on to start gathering air quality data fit for reporting and decision-making. Remote diagnostics keep downtime to a minimum, ensuring you’re fully compliant. 

    The Praxis/Cube is ideal for:

    • Boundary monitoring for construction and demolition
    • VOC monitoring at mining or drilling platforms
    • Environmental monitoring at lime & cement kilns
    • UK Construction Section 61 notices
    • Environmental dust assessments

    Announcing: Precision indoor & outdoor air quality monitoring in one device

    South Coast Science is pleased to launch Praxis/Cube2, a 2 gas version of the original Praxis/Cube. It offers the same high levels of precision whether monitoring indoor or outdoor pollution levels.

    What’s the lifetime cost of your air quality monitors?

    Many commercial air quality monitors heat the air prior to sampling, but South Coast Science has developed a more elegant solution to the problem that saves on maintenance costs, whilst also improving data accuracy.

    Monitoring VOCs at Drill Pads in Denver, USA

    Colorado accounts for 4% of US crude oil production, according to the US Energy Information Administration (EIA). Whilst gas drilling is important for global energy security, the drilling process also creates air pollution and the potential for harm to health. 

    Machine Learning (ML) boosts performance of low-cost air quality sensors

    Recent research using low-cost Praxis/Urban air quality instruments uses ML data correction methods to improve field performance.  The research is linked with Oxford’s OxAria project and […]
