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.

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.

Cartridge Configurations

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).
