Air Quality Sensor
The Zephyr® is a compact and lightweight ambient air pollution sensor that accurately measures harmful gases and particle matter.
Zephyr® sensors provide detailed air quality measurements in real-time to help identify pollution hotspots at a localised level such as busy road junctions. Extensive networks can be easily deployed for city-wide analysis and optimisation of pollution-lowering initiatives.
Every unit is GPS enabled so can be used as a static or mobile sensor for use whilst walking, cycling or in a vehicle.
How it Works
Static Zephyr® deployments in Coventry City Centre | Coventry City Council, 2019
Replaceable Cartridge System
All Zephyr® sensors operate on a replaceable cartridge system. Options include either a standard or enhanced cartridge depending on requirements.
As part of our ongoing service pack we replace cartridges as required to maintain sensitivity and accuracy of measurements.
The Zephyr® is designed to allow for an active refresh of air within the cartridge for a true and accurate insight into ambient air quality.
All sensors can be used as a mobile or static device. Install the Zephyr rapidly onto a post, vehicle or even a backpack, and the in-built GPS will provide accurate positional information for each measurement.
We calibrate every Zephyr® air quality sensor prior to dispatch and our calibration performance is tested against reference standard analysers. Following successful calibration we provide you with a calibration certificate for your Zephyr®
Air Quality Web App
View, analyse and download your measured Zephyr® data in the newly designed, user-friendly MyAir® air quality web app.
A first to market innovation which includes a global air quality model, air quality management areas (AQMAs) and DEFRA air quality reference data free of charge.
Your Zephyr® air quality data can be accessed directly via our API in a range of formats including json and csv.
In addition, our Zephyr® web portal allows you to interact with data from all your deployed Zephyrs easily and intuitively.
Included within the Zephyr® service pack, our web portal enables swift access to your air quality data.
Calibration & Testing
We calibrate and test every Zephyr® sensor and will notify you when it's ready to start measuring.
We carry out remote monitoring of sensor degradation to ensure there's no loss in data quality.
As part of our service pack we supply replacement cartridges and even recycle your old ones. Contact us to find out more about our 1, 3 and 5 year cartridge plans.
Full warranty on any manufacturing faults.
