Based on the light scattering method, same as particle counters, it detects air borne particles from cleanliness class 100,000 to 1,000,000.

• Stable and sensitive detection of not only cigarette smoke but house dust which are considered as indoor asthma triggers.
• Air is self-aspirated by the air current generation mechanism with a built-in heater.
• Easy maintenance. Sustainable high sensitivity.
• Easily detects the particles sized over 0.5µm (approx).
• Dual output of Pulse and analog Voltage.
