1. Product introduction

In order to control particulate pollution, the environmental protection department has increased the continuous online monitoring of pollutants emitted from the chimneys of industrial enterprises, including the measurement of smoke emission speed, particle concentration, and total emission. Although the traditional filter membrane sampling and weighing method is recognized as a detection method with relatively high reliability of measurement results, this method is extremely inefficient and cannot reflect the dynamic emission of particulate pollution in real time. has a certain risk. Therefore, the on-line continuous monitoring technology of smoke and dust with a high degree of automation has become the main monitoring method of particulate pollution. Light scattering particle concentration measurement technology has the characteristics of high sensitivity, fast response and small size, and has good development potential and application value in the field of particle pollution monitoring. It is suitable for industrial enterprises in cement, hydropower, steel, metallurgy, oil refining, aluminum, petrochemical, paper, glass and other industries.
