Field-side device according to relevant national technical agreement, real-time monitoring of the concentration of dust monitoring point signal transmission to the monitoring platform, when the monitoring data to meet the department set alarm conditions, start the alarm facilities, monitoring platform for monitoring data storage, statistics, analysis, processing, and provide data to support decision-making basis for air quality management. Fourth, dust analysis module principle (laser scattering method): using laser light to improve the response time, the concentration of particulate matter is not affected by the conversion factor of color to ensure the accuracy of the measurement data. Built-in optical scattering board to ensure high stability. Instrument designed to replace the particle cutter, to achieve a PM10, PM5, PM2. 5, TSP various particle separator cutter compatible. By filter sampler, to achieve a continuous monitoring dust concentration compatible with the sampling filter, you can analyze the composition of the collected particulate matter in order to convert a mass concentration factor K value of the property. Constant current controller designed to ensure a constant flow sampling, cutting the curve correctly. Shielding gas curtain particular, to avoid the dust on the core component - contamination of the optical system, to ensure high reliability. Through computer software to automatically adjust the instrument zero, improve measurement accuracy, convenience to users.
