Next generation pollution monitoring
For decades, aerosol instruments ranging from regulatory-grade systems down to simple smoke alarms have depended on the proven reliability and unique advantages of bipolar charging. Atmose leverages this principle in a revolutionary way to enable scalable ultrafine monitoring through deployable and affordable systems.
Electrometer-based detection using bipolar ion source
Ambient Ultrafine Monitor (AUM-BE1)
Accurate
The AUM's bipolar charging provides distinct advantages in stability and accuracy compared to conventional unipolar charging across a wide range of operating conditions.
Health-relevant metrics
The AUM measures lung-deposited surface area (LDSA), a metric related to what matters most–our health.
Fast response
Ultrafine particles are the most dynamic subset of particles. The AUM measures at 1 Hz to make every second count.
Cost-effective
Due to the complexity of measuring the smallest particles, ultrafine sensors have never been low-cost. Our patented method is the first to harness bipolar charging in this simple form to measure the smallest particles.
Field-ready
Approaching the size of a conventional smoke alarm, the AUM is a compact, low-power solution which can be integrated into even the smallest of air quality platforms.
Innovative solutions
Exposure to fine aerosol particulate matter, quantified as PM2.5, is the leading environmental risk factor for premature disease and death worldwide. The smallest of these particles, ultrafines, often have large total surface area and penetrate deep into human lungs. Ultrafines are mostly invisible to low-cost optical sensors, therefore new approaches are needed for widespread monitoring.
System integration
Atmose’s ambient ultrafine monitor (AUM) provides real-time measurements of the smallest aerosol particles in both indoor and outdoor environments. The AUM electrically charges particles with positive and negative gas ions, removes the ions, and detects the charged particles.
