Product Details
Laser Dust Sensor KGD-PM-211
Product Introduction
The KGD-PM-211 module of the laser dust sensor adopts the principle
of optical scattering. It can accurately detect and calculate the
number of suspended particulate matters of different particle sizes
in the air per unit volume. Equipped with KACISE's unique
intelligent dust source identification and an air pump with a
stable flow rate, it can achieve the real-time output of the mass
concentrations of particulate matters PM2.5, PM10, and TSP.
Product Features
- Simultaneous output of PM2.5, PM10, and TSP
- Industrial-grade laser, with high reliability
- Anti-ash accumulation design, meeting the measurement requirements
in high-dust environments
- Small size and easy to install
