Lower cost, higher density, smart and accurate  measurement of common pollutants in urban air.

A ‘low cost’ air quality monitoring solution, the SEN024 gives you air quality information that’s scientifically credible, and relevant to where you live, work and play. Set up as a single device or deployed in a network of monitors, the SEN024 reports key urban pollutants in real-time.

Accurate air quality data passes through a flexible communications platform and is available to view through our software or yours. Throughout you will be supported by a team of air quality experts who are leading innovators in the field.

  • Detail

Features, Benefits & Functions

  • Smart cities who want air quality and environmental data to show that their city is an attractive place to live, work and invest in.
  • Air quality professionals who need a real-time alternative to diffusion tubes and samplers, or a more affordable alternative to analysers.
  • Community groups who need a cost-effective way to gather scientifically credible air quality data that will be treated with respect by their stakeholders.
  • Educators who want students to learn about air pollution in a way that supports STEM subjects and promotes environmental awareness.
  • Health and safety managers who need to demonstrate that they are providing a safe environment for the people in their care. Researchers who want to collect as much scientifically robust data as possible on a limited budget.
  • A small weather-proofed monitor that measures and reports key urban air pollutants and environmental parameters in real-time. 
  • A flexible communications platform that transfers real-time data wirelessly, and gives you access through an API. 
  • A web interface accessed via browser on your phone, tablet or PC, where you can see all your data in one place and set alerts on parameters of concern.  
  • A remote technical support service that maximises the useful life of the sensors while keeping high quality data flowing. 
  • Active fan-sampling (better than simple diffusion). 
  • best in class GSS ozone sensor Interference-free NO2 measurement. 
  • Auto correction of humidity effects on PM2.5 measurement. 
  • Anti-static inlet to avoid loss of particulate during sampling. 
  • Ability to be calibrated remotely. 
  • Data correction and optimization is done on the monitor, not in the cloud. We believe this ensures the integrity of the data and helps to maintain confidence in the measurement.
