便携式水质检测仪性能综合评价方法研究

目前便携式水质检测仪品种繁多，各种技术指标和性能尚无统一评价标准，导致仪器性能良莠不齐，监测数据质量难以保证，无法满足管理部门对环境监测数据的要求，检测机构在采购过程中也难以选择。为解决这一问题，建立了便携式水质检测仪综合评价方法，确定了综合评价指标，制定了综合评价标准，选择相关仪器及相关项目进行综合评价。结果表明，大部分便携式水质检测仪器在便携性、操作简易性等方面做得比较好，而在准确度、精密度等方面还有待提高。该评价方法综合考虑了影响便携式水质检测仪的各项因素，能够为全方位评价、选择便携式水质检测仪提供参考。

Research on Comprehensive Evaluation Method of Portable Water Quality Detector

At present， there is no unified evaluation standard for various technical indicators and performance of portable detectors， which leads to the intermingled performance of the instruments， the quality of monitoring data is difficult to be guaranteed， and the requirements of the management department are not met， and it is also difficult for the testing agency to choose during the procurement process. To solve this problem， this study established a comprehensive evaluation model of portable detector， determined the comprehensive evaluation indicators， formulated the comprehensive evaluation criteria， and selected relevant instruments and related items for comprehensive evaluation. The results show that the evaluation method comprehensively considers various factors affecting the portable detector and can be well applied to the evaluation and selection of portable detector. From the evaluation results， it is found that most portable water quality detection instruments do well in portability and ease of operation， however， the accuracy and precision need to be improved. The current evaluation method takes various factors that impact the performance of portable detectors into consideration， which provides reference to evaluation and selection of portable water quality detector.
