Sensing ultrafine particles for our environment and health

The fine particles in smoke, smog and haze are a leading cause of premature death and have significant environmental and climate impacts. Smaller, ultrafine particles have further health impacts due to their higher concentration, larger surface area and deeper penetration into the lungs. Existing measurements of ultrafine particles are prohibitively costly, cumbersome, or compromise on accuracy and reliability.

Our patent-pending technology enables our customers to gain a new understanding of the localized effects of fine and ultrafine particles to protect health, preserve the environment and limit climate impacts.

Atmose is developing a range of compact sensors for real-time measurements of fine-to-ultrafine particles in both indoor and outdoor environments. Our sensors are uniquely accurate and reliable for their compact form and provide critically needed metrics for ultrafines. We are engaging with providers of air pollution monitoring networks and research laboratories to integrate our sensors into their measurement platforms.


Our commitment to innovation and excellence is what sets us apart.

While performing cutting-edge research in aerosol science and technology at the University of Cambridge, we found that localized measurements of ultrafine particles were elusive. We've created new ways to make them a reality.
