Pegasor Airam – Real-Time Ultrafine Particle Monitor
Pegasor Airam is a standalone ultrafine particle monitor designed for ambient and outdoor air quality monitoring. The system provides real-time measurements of particle number concentration (PN), lung deposited surface area (LDSA), particle mass (PM), and particle size. The Airam goes beyond traditional PM10 and PM2.5 measurements, aligning with the new European Union Ambient Air Quality Directive, setting stricter limits on key air pollutants, including ultrafine particles (UFPs). The new directive aligns more closely with the World Health Organization’s (WHO) air quality guidelines, aiming to reduce pollutants which are known to cause respiratory and cardiovascular issues.
The Airam system is powered by the Pegasor Particle Sensor PPS-G2. The PPS-G2 operation is based on the unique Pegasor technology that combines diffusion charging with the “escaping current” technology. With this method, particles flow through the sensor and are not collected inside the system, making the maintenance intervals extremely long, even up to years in air quality monitoring applications. The Pegasor Airam system is built within a weather-proof cabinet and equipped with extensive self-diagnostics. A heater for the sensor module is included inside the system to prevent condensation, and the integrated pump with needed filters ensures standalone operation without the need for external air supply units. The data is saved via Ethernet, Modbus, 4G or Wi-Fi to external laptop or remote location. The Pegasor Cloud Portal service is also available for remote operation and data storage.
What are ultrafine particles?
Ultrafine particles (UFPs) are airborne particles smaller than 100 nanometers. Unlike PM2.5 and PM10 measurements that focus on particle mass, ultrafine particles are typically monitored by particle number concentration because they contribute little mass but can occur in extremely high quantities.
Common sources of ultrafine particles include vehicle emissions, airports, shipping activities, industrial processes and combustion sources. Because of their small size, ultrafine particles can penetrate deep into the respiratory system, making accurate monitoring increasingly important for air quality research and regulatory compliance.
Pegasor Airam provides continuous real-time monitoring of ultrafine particles through measurement of particle number concentration (PN), lung deposited surface area (LDSA), particle mass (PM) and particle size.

Q&A
An ultrafine particle monitor measures airborne particles smaller than approximately 100 nm. Pegasor Airam provides particle number concentration (PN), LDSA, particle mass (PM) and particle size information in real time.
PM2.5 monitoring focuses on particle mass. Ultrafine particle monitoring focuses on particle number concentration because ultrafine particles contribute very little mass despite being present in extremely high quantities.
Yes. The system is designed for outdoor operation with a weatherproof enclosure, self-diagnostics and sensor heating.
No. Its flow-through design minimizes contamination and enables very long maintenance intervals.
No. The Pegasor Airam uses charging technology, meaning it requires zero working fluids, no alcohol, and no radioactive sources.
Yes. The system supports Ethernet, Wi-Fi, 4G connectivity and the optional Pegasor Cloud Portal.
Yes, it is an ideal tool to support the Directive’s UFP monitoring goals. The Directive mandates Ultrafine Particle monitoring at supersites, specifically requiring Particle Number (PN) concentration and Size Distribution. The Directive also pushes for dense monitoring networks and allows “indicative measurements” where strict reference methods are too expensive or difficult to maintain.
For PN Concentration: The Pegasor Airam is fully capable. It measures Total Particle Number PN for >10nm in real-time, meeting the critical detection range of the Directive.
For Size Data: While supersites typically use complex spectrometers for full distribution, the Airam provides Mean Particle Size and LDSA. This makes it the perfect “scalable” instrument to deploy around supersites to map actual human exposure across a city, where deploying expensive spectrometers is impossible.
