Product Details
Dust Concentration Detector KGD-OPM-211
Product Introduction
The Dust Concentration Detector KGD-OPM-211 applies the principle
of optical scattering. It can accurately detect and calculate the
number of suspended particulate matters with different particle
sizes in the air per unit volume. It is equipped with KACISE's
brand-new patented technology of intelligent dust source
identification, and combined with an air pump with a stable flow
rate, it realizes the real-time detection and output of the mass
concentrations of particulate matters PM2.5, PM10, and TSP.
Product Features
- Industrial-grade laser, featuring high reliability
- Constant current sampling control to ensure a constant sampling
flow rate
- Real-time measurement of the mass concentrations of PM2.5, PM10,
and TSP, and the detection data is updated once every second
- Operates within a wide temperature range for enhanced stability
