Airborne Particle Counter

Principle: The particle counter uses a laser light source and collection optics for particle detection. Particles scatter light from the light source in the direction of the collection optics. The collection optics focuses the light on a photoelectric cell that converts the bursts of light into electrical pulses. The pulse height is a measure of particle size. Pulses are counted and their intensity is measured for particle sizing. Results are displayed as particle count in the specified size channel. Features: 1. 0.1cfm (2.83lpm) flow rate; 2. Large LCD display; 3. 2 counting modes; 4. Six particle-size channels (0.3, 0.5, 1.0, 2.0, 3.0, 5.0µm); 5. Date and time display; 6. Federal Standard 209E Calculation ; 7. Multiple print-mode; 8. Data conversion (cu.ft. and cbm); 9. Data storage.
