The KGD - YQ - 540 Flue Gas Dust Sensor Module adopts the optical scattering principle and can accurately detect the mass concentration of suspended particulate matter in the flue gas per unit volume. When the dust particles in the sample gas pass through the laser beam in the constant - temperature measuring gas cell, a light scattering signal is generated. Then, the photoelectric converter converts the scattered light signal into an electrical signal, and the real - time particulate matter mass concentration data is obtained by calculating the relationship between the signal intensity and the concentration. The product complies with the detection requirements of the national standard HJ 76 - 2017 "Technical Requirements and Detection Methods for Continuous Emission Monitoring Systems of Flue Gas (SO₂, NOₓ, Particulate Matter) from Stationary Pollution Sources.

• High sensitivity, with a minimum detection limit of up to 0.01mg/m³.
• Modular design, compact structure, and easy to install.
• Adopts an ultra - low range design, suitable for low - concentration flue gas detection.
• Constant - temperature heating effectively prevents condensation.
