Zephyr®

Air Quality Monitor

The Zephyr® is an award-winning, certified, indicative ambient air quality monitor that accurately measures harmful gases and particle matter. 

​

Zephyr® monitors 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.

Zephyr® Subscription

We offer an all inclusive pollution monitoring subscription service for business including hardware, servicing, data access and field work.

Zephyr® Rental

Short-term, flexible air quality monitoring project? Take a look at our new Zephyr® rental service available in the UK only. 

Air Quality Data for Whole Cities

Deploy a network of Zephyr® monitors as a cost effective way of identifying pollution hotpots and trends across a town or city. 

​

The new white colourway ensures effective performance for Zephyrs even when deployed in hotter climates.

Replaceable Cartridge System

Zephyr® monitors operate on a replaceable cartridge system. Options include a range of standard and enhanced cartridges depending  requirements.

 

As part of our ongoing service 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 monitors can be used as a mobile or static device.  Install the Zephyr® 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 monitor 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®. 

​

The new white Zephyr® ensures that when deployed in areas of high temperatures, there is effective sensor performance. 

​

Certified against the UK Environment Agency's MCERTS Scheme (Indicative MCERTS).

Data Access in the MyAir® Web App

View, analyse and download your measured Zephyr® data in the EarthSense MyAir® web app.​

​

The app also has a host of features such as source apportionment, 3-day pollution forecasting, alerting, Air Quality Management Area (AQMA) overlays and country-wide MappAir® modelled data for added context to your localised air quality measurements.

Integrate Data with a Comprehensive API

Zephyr® air quality data can be directly integrated into third party systems via our API in a range of formats including Json and csv.  

​

Integrate air quality measurements into traffic models, smart city applications and more.
