In China, with the proposal of the "dual carbon" target and the arrival of the "14th Five Year Plan" period, the development of ecological environment has accelerated, and the control of air pollution is gradually pursuing refined supervision. Particles of different sizes come from different sources, behave differently in the atmosphere, have different impacts on the environment and climate, and have different effects on human health. Understanding the sources and properties of particles of different sizes is crucial for developing effective pollution control strategies.

At an important turning point in the refinement of atmospheric monitoring, the strong support of monitoring equipment is indispensable. Multi channel dust concentration detector, also known as aerosol monitor, can simultaneously measure the mass concentration of multiple particles of different sizes. It can analyze the characteristics of particles, trace the main causes of particle pollution, and implement targeted governance measures.

The SND1000 multi-channel dust detector is based on advanced single particle laser scattering principle to monitor the concentration of particulate matter in the environment in real-time online, including PM1, PM2.5, PM4, PM10, and TSP, achieving simultaneous measurement in five channels. Novasensor multi-channel dust detector has a battery life of over 20 hours, ensuring long-term stable operation and becoming a shining eye for environmental dust monitoring. It can be widely used in professional scenarios such as indoor air quality monitoring, aerosol research, pollution source analysis, migration particle measurement, clean rooms, food and industrial workshops, etc. It helps environmental protection departments, factory workshops, and research institutions efficiently and continuously monitor the concentration of particulate matter in the air in real time, providing a healthier and cleaner working and living environment.

Compared to traditional aerosol monitors, the SND1000 multi-channel dust detector has higher measurement accuracy and particle size resolution, as well as stronger resistance to humidity effects. The multi-channel dust detector uses industrial grade lasers and photosensitive components, carefully focused optical and pneumatic structures, as well as a new generation of high-frequency weak model processing circuits and high-precision particle recognition algorithms, greatly improving the range and accuracy of particle size recognition. It can adapt well to changes in environmental particle composition and provide relatively accurate measurement results even in extreme weather conditions such as sandstorms.

The SND1000 multi-channel dust detector adopts an active sampling method, and the sampling component uses a high-performance air pump, which can meet long-term long-distance high negative pressure sampling. Aerodynamic correction, self inspection of light and gas paths, insensitive to vibration, ensuring system reliability and stability. The multi-channel dust detector adopts a multi-core design, which improves the service life of the instrument in harsh environments and greatly reduces manual maintenance workload. The comprehensive and professional design ensures good stability in long-term continuous monitoring for 7 * 24 hours in various occasions.

The data comparison between SND1000 dust detector and standard instrument (Belta ray method) under sandstorm weather shows a correlation coefficient of r=0.96, which can achieve measurement results that are almost consistent with the standard instrument. The quality is comparable to international brands, the price is more affordable, domestic substitution can be achieved, it has a high cost-effectiveness, and maintenance is more convenient.

The SND1000 multi-channel dust detector meets the technical requirements of the JJF1190-2008 "Dust Particle Counter Calibration Specification" issued by the State Administration of Metrology, and has passed the CPA metrological certification. It is a professional and reliable dust detector that can meet the refined monitoring needs of many fields.
