Product Details
Online Dust Concentration Tester KGD-OPM-212
Product Introduction
The KGD-OPM-212 Online Dust Concentration Tester 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. It is equipped with
KACISE's brand-new intelligent dust source identification
technology and combined with an air pump with a stable flow rate,
enabling the real-time detection and output of the mass
concentrations of particulate matters PM1.0, PM2.5, PM10, and TSP.
Product Features
- Brand-new intelligent dust source identification technology
- Industrial-grade laser, with high reliability
- Constant current sampling structure to ensure a constant sampling
flow rate
- Real-time measurement of the mass concentrations of PM1.0, PM2.5,
PM10, and TSP, and the detection data is updated once every second
- Operates within a wide temperature range for greater stability
Technical Parameters

traceability system benchmarked with Wuhan National Station. If
there are differences in the measured values in other regions, the
coefficient calibration is required according to the local
distribution of dust particulate matters) |
