Minimal Round Edge Design
Airam not only offers accurate air quality measurements but its simple and modern design fits into any space.
Intuitive Signal Lighting
The Signal Lighting in the left corner shows the fine dust levels in four colors.
High-Precision Sensor that Detects Even Ultra-Fine Particulate Matter
Using a laser scattering technology, Airam detects 0.3~10㎛ particulates with high precision. Instead of showing converted values, Airam show actual particulate levels in real-time.
- Ultra Fine Particulate (PM1.0), Fine Particulate (PM2.5), Coarse Particulate Matter (PM10)
User-Centered Design
The LCD touch screen with minimal buttons and simple, intuitive UI allow you to monitor air quality right away.
Various Screen Modes
Airam offers multiple screen modes you could switch between (particulate matter, CO2, etc).
Enhanced IoT System
Airam uses it own cloud server and app to manage air quality data and air monitoring system.
