I. Summary of Pollen Automatic Measurer The Pollen Automatic Monitoring System is an advanced monitoring equipment system developed by our company, capable of quickly and accurately identifying and detecting pollen concentration. It utilizes scattered laser beams from semiconductor materials and particle counters to detect the quantity of pollen and its concentration in the air. The optical system employs both forward and side scattering of semiconductor lasers for the judgment of pollen and cellulose, and data transmission over long distances can be achieved through software. It eliminates the繁琐 steps of manual sampling and microscope counting, achieving system automation and significantly reducing the workload of researchers while enhancing the reliability and accuracy of the data results. It provides efficient and convenient data services for medical diagnosis and scientific research, protects allergics from high-concentration pollen irritation, and helps in planning daily activities reasonably. LJHF3000 Automatic Pollen Online Monitoring System: The main characteristics and distinctions of pollen typically range between 10μm to 150μm in size. Complex morphology. Wind-pollinated pollen: smooth surface. Pollen carried by insects: sticky, with sharp edges and spines. Similar chemical structure: spectroscopy is ineffective. Under a microscope, it appears semi-transparent.Technical Specifications:
