This study presents a comprehensive evaluation and selection framework for extremely low-frequency electromagnetic field (ELF-EMF) measurement instruments. Recognizing the diversity of application environments and technical constraints, the framework addresses the challenges of selecting appropriate tools for specific scenarios. It integrates a structured, quantitative approach through a weighted scoring matrix that evaluates instrumentation across six criteria: monitoring duration, sensitivity, environmental adaptability, biological/regulatory relevance, usability, and cost. Complementing this is a logic-based flowchart that visually guides decision-making based on user-defined operational needs. The framework is applied to a realistic occupational case study, demonstrating its effectiveness in producing evidence-based, scenario-sensitive instrument recommendations. This method provides stakeholders with a transparent and adaptable tool for ELF-EMF device selection.
本研究提出了一个用于极低频电磁场（ELF-EMF）测量仪器的综合评估与选择框架。认识到应用环境的多样性和技术限制，该框架解决了为特定场景选择合适工具的挑战。它通过加权评分矩阵集成了一种结构化的定量方法，该矩阵根据六个标准评估仪器：监测持续时间、灵敏度、环境适应性、生物/法规相关性、可用性和成本。与此相辅相成的是一个基于逻辑的流程图，它根据用户定义的操作需求直观地指导决策。该框架应用于一个实际的职业案例研究，证明了其在生成基于证据、对场景敏感的仪器建议方面的有效性。这种方法为利益相关者提供了一个用于ELF-EMF设备选择的透明且可适应的工具。
