Zephyr®
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 pollution data used to aid the development of smarter and cleaner towns and cities.

How it Works
Air Quality Data for Whole Cities
Simply deploy a network of Zephyr® sensors across your city as a cost effective way of identifying pollution hotpots and trends.

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.
Active Sampling
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.
Mobile &
Static Use
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.
Sensor Performance
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®

MyAir®
Air Quality Web App
View, analyse and download your measured Zephyr® data in the newly designed, user-friendly MyAir® air quality web app.
Featuring first-to-market innovations including a global air quality model, air quality management areas (AQMAs), source apportionment, forecasting and DEFRA air quality reference data free of charge.
Comprehensive API
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.
