Recently introduced outdoor ultrafine particle monitor provides real-time air quality and weather data for long-term monitoring

QuantAQ has launched the MODULAIR-UFP, a highly advanced sensor designed to measure ultrafine particles (UFPs) in outdoor environments. This device enables the collection of new air quality data, supporting research, regulatory oversight, and community monitoring efforts. Designed for continuous use outside laboratories, the MODULAIR-UFP measures total particle number concentrations ranging from 0 to 100,000 particles per cubic centimetre, ensuring stability with minimal maintenance over extended periods.

David Hagan, QuantAQ’s CEO and Co-founder, commented, “Until now, ultrafine particle monitoring has been highly constrained and difficult for long-term outdoor uses. The MODULAIR-UFP brings these critical measurements into the field with precision, reliability, and ease.”

Each unit includes a Gill® Weather Station that delivers real-time meteorological data, such as wind speed, wind direction, ambient temperature, and relative humidity. Combining these parameters improves the understanding of particulate measurements, allowing for more detailed analysis of local air quality, especially in complex urban and industrial settings.

“With its compactness and portability, the MODULAIR-UFP opens up exciting new research possibilities,” stated Dr. Dan Westervelt, an Associate Research Professor at Columbia Climate School’s Lamont-Doherty Earth Observatory, who is also a QuantAQ customer. “We are particularly looking forward to understanding emissions of ultrafine particles near a major New York City highway as a function of vehicle type, fuel quality, driving conditions, and vehicle age.”

Unique among existing UFP measurement technologies, the MODULAIR-UFP uses a water-based, pulsed condensation particle counter (CPC) method. The sensor's compact design, simple installation, and low power use make it ideal for long-term monitoring. Additionally, the system has a predictive alert to notify operators when the water reservoir needs refilling, helping to minimise data collection disruptions.

Data collected by the MODULAIR-UFP can be accessed remotely in real-time through the QuantAQ Cloud™ platform, enabling high-resolution analysis across individual or multiple monitoring sites. This offers valuable flexibility and control for various stakeholders, from academic researchers studying exposure near roadways to municipal agencies tracking pollution patterns and community groups advocating for air quality.
