Handheld detector: an efficient tool for multi-scenario environmental monitoring
In industrial safety, environmental governance and health management, handheld detectors have become indispensable monitoring tools due to their portability, high precision and intelligent functions. The SDL511 series and SDS039-FC-H dust particle counters launched by Shandong Nofang cover multiple needs from dust concentration to cleanliness detection. Their application scenarios and technical advantages are as follows:
1. Industrial safety: protecting the production environment and workers' health
In high-dust environments such as cement plants and mines, the SDL511-031 portable dust detector can quickly locate areas exceeding the standard through three-channel detection of PM2.5, PM10 and TSP (range up to 100mg/m³). Linking its sound and light alarm function with the ventilation system can reduce the risk of explosion; the 7 million data storage capacity supports long-term exposure analysis, helping companies optimize protective measures and meet occupational health standards.
The SDL511-069 multi-channel particle detector has a new PM1.0 detection channel with a resolution of 0.1μg/m³, which is suitable for monitoring workshop environment and atmospheric environmental protection. Its isokinetic sampling head simulates the human breathing trajectory, accurately assesses the actual exposure level of workers, and provides a scientific basis for the prevention and control of occupational diseases.
2. Environmental governance: accurate control of dust and air pollution
For construction site and road dust, the SDL511 aerosol meter is equipped with a humidity calibration module to eliminate environmental interference and ensure the accuracy of PM2.5/PM10 data. After the optional 4G module and GPS positioning, data is uploaded to the cloud platform in real time. The environmental protection department can remotely monitor pollution sources in multiple regions and quantify the effects of water sprinkling and dust reduction. For example, by comparing the data before and after construction, the control effect can be accurately evaluated.
3. Indoor air and clean room management: ensuring health and production safety
In indoor scenarios such as homes and hospitals, SDL511 evaluates the performance of the fresh air system through laser detection (0.3μm particle efficiency 70%), and users can generate concentration trend charts to optimize ventilation strategies.
The SDS039-FC-H handheld dust particle counter is designed for clean rooms and supports six-channel particle counting from 0.3 to 10μm, in line with ISO21501 standards. Its 4.3-inch touch screen and Bluetooth printing function help the electronics and pharmaceutical industries quickly complete cleanliness certification and ensure compliance with the production environment.
4. Scientific research and emergency response: Flexible response to complex needs
The SDL511 series supports external hoses and IoT modules, and can be integrated into drones or mobile platforms for atmospheric pollution diffusion research. Its laser scattering principle is highly related to the β-ray method, and the data reliability is strong, which is suitable for academic demonstration.
Conclusion
From dust explosion prevention and control to clean room certification, from dust control to healthy home, handheld detectors break through the limitations of traditional equipment with their lightness and precision. Nofang SDL511 and SDS039 handheld series not only improve monitoring efficiency, but also provide a technical foundation for sustainable development through data-driven decision-making.
