Product Details
Laser Dust Sensor KGD - PM - 112
Product Introduction
The KGD - PM - 112 laser dust sensor is based on the principle of
optical scattering. It adopts a full-metal shield and an ultra-thin
(12mm) design. It can accurately detect and calculate the number of
suspended particulate matters with different particle sizes in the
air per unit volume, and through mathematical algorithms and
scientific calibration, it can output the mass concentrations of
PM1.0, PM2.5, and PM10 particulate matters in real time.
Product Features
- The minimum resolvable particle size is 0.3μm.
- Outputs PM1.0, PM2.5, and PM10 in real time.
- Constant current sampling structure.
- High accuracy, high sensitivity, and fast response.
- Full-metal shielding, with good anti-interference ability.
- Ultra-thin design, with a height of only 12mm.
