Complete cabinet installation, cabinet material: stainless steel 304L. Comes with installation bracket and connecting accessories. Environmental protection level: IP54.

Measurement objects: industrial waste gas, smoke, dust

Measurement principle: Based on the principle of forward light scattering, the highly stable laser emitted by the laser is collimated and then injectedThe measurement room generates forward scattered light when the laser beam meets the particles. The scattered light is received by a lens and transmitted through a signalThe optical fiber is imported into the photodetector.After ultra-high sensitivity photoelectric signal conversion, the scattered light signal is transformed into a telecommunication signal proportional to the concentration of particulate matterNumber, output the concentration value of particulate matter through a specific algorithm.Extraction heating return gas path structure, which can be used in situations where the measured gas contains water mist;Optical path structure, with extremely high sensitivity and resolution;Automatic zero point and automatic span calibration; Technology: Jiuzhou Pengyue Zhang Haitao

The structure and calculation method of the blowback and air curtain held, resistant to window pollution;

Industry applications: Online monitoring of emissions (thermal power, steel, metallurgy, cement, petrochemical, ceramics, aluminum, nuclear)Electricity can also be widely used for continuous measurement of particulate matter in process control, hygiene, safety, scientific research, and other fieldsVenue
