Ambient air quality
The South Coast Science Praxis/Urban offers an out-of-the-box solution for urban air quality monitoring. The Praxis answers both the challenge of capturing accurate data in variable climate conditions and the need for fine-grained air quality monitoring networks.
The Praxis/Urban offers ultra-low noise sensing for gasses (CO, H2S, NO, NO2, O3, SO2, CO2) and particulates (PM1, PM2.5 and PM10). The device supports multiple analysis techniques including any sampling rate and real-time access.
Consistent device function is possible within a broad climate range (T/rH) with a casing rated for hostile environments. This includes continuous operation for up to 2 hours in the event of external power loss.
Use Praxis to build a high-density air quality network using low-cost, individually baselined devices that use open-source device firmware for highly customisable sensing, data delivery and analysis.
Delivery: available now.
Environmental Health/Smart CityThe Praxis/OPCube is a small rugged device that measures both gas and particulate matter (pm1, pm2.5, pm10) and is an effective monitor for low-cost screening, construction dust and local authority investigations. The Praxis/OPCube uses Alphasense sensors throughout and can be supplied with one (soon to be two) of their standard A4 electrochemical gas or VOC sensors.
Sensor data including temperature and humidity can be stored on the device or transmitted in real-time via the 4G modem to the South Coast Science cloud. Open-source device firmware is supplied for highly customisable sensing and analysis. To maximise ROI over the life of the instrument, upgrades to device firmware and diagnostics are supplied remotely (if South Coast Science data analytics is used).
Delivery: available now.
Products In Development
An exciting product roadmap is in place, with new instruments for personal exposure monitoring, environmental health and commercial offices due for launch over the next six months.

Odour monitoring in the Wastewater sectorEffective odour management in the wastewater treatment industry starts with accurate measurement to establish baselines. This is so that the impact of process design, treatment type and weather patterns amongst other influences can be understood.
However, ppb-level measurement of H2S (and other) odour has traditionally been expensive, relying on very expensive equipment which has complex service/calibration requirements and cannot be left unattended on a fence line or is unsuitable as a genuinely portable device.
The Praxis/GasCube is a multi-gas device designed for odour monitoring in a variety of environments.
- Up to four gases from NO, CO2, VOC, H2S
- Environmental range from -40 to +50 C
- Battery/solar or mains powered
- Applications include: wastewater, petrochem, landfill, poultry farming.
The exact specifications of the Praxis/IAQ are being refined in discussion with customers. South Coast Science invites further input.
Indoor air quality
The most accurate and flexible internal air quality monitoring device for real-time reporting. Serviced office managers are, rightly, more concerned about indoor air quality than they’ve ever been. The need to control the spread of airborne pathogens, as well as a growing realisation that air quality can affect tenants’ productivity, are fuelling investment in indoor air quality management.
The Praxis/IAQ device for Indoor Air Quality monitoring is part of the South Coast Science technology roadmap and will be developed in accordance with the WELL building standard. This can be used together with either the Praxis/Urban or Praxis/OPCube, so that both indoor and outdoor air can be comprehensively monitored and therefore managed.The exact specifications of the Praxis/IAQ are being refined in discussion with customers. South Coast Science invites further input.
Personal exposure monitoring
To monitor an individual’s exposure to pollution over the course of a typical day, the monitoring device must be highly portable as it will travel with a person indoors and out, almost certainly via several modes of transport.
The Praxis/Handheld may be ‘on the move’ for several hours before being returned to base and because of this, it is equipped to store large amounts of data until it reconnects with a wi-fi network. Alternatively, the user can upload to the cloud in real-time via a mobile phone hotspot
- Can be hand-carried, attached to a backpack, or for in-vehicle use.
- Environmental range from -40 to +50 C.
- Any one gas from CO, H2S, NO, NO2, O3, SO2 and undifferentiated VOCs. (CO2 available later.)
- PM1, PM2.5 and PM10.
