新型环境监测仪器户外小型水质自动监测站性能研究

随着中国地表水水质自动监测站建设工作的大力推进，近几年一种体积小、集成度高、功能完备并且直接应用于户外的小型水质自动监测站设备成为研发和应用热点。为了探究目前市场上户外小型水质自动监测站产品的仪器性能和技术特征，笔者选取6种型号的户外小型水质自动监测站进行功能检查和性能测试。结果表明：户外小型水质自动监测站具备采配水、预处理、水质多参数分析、数据传输等功能；不同参数标准溶液的测定结果具有较高的准确度和精密度，不进行任何维护的情况下整个系统能够在户外连续稳定运行一个星期以上。

Study on the Performance of a New Type of Environmental Monitoring Equipment:Outdoor Small Water Quality Automatic Monitoring Station

The construction of water quality automatic monitoring stations has been promoted vigorously in China.Outdoor small water quality automatic monitoring station has aroused a great deal of attention because of its small size,high level of integration,complete function and outdoor use in recent years.In order to investigate the performance and technical characteristics,six types of outdoor small water quality automatic monitoring stations were used for function check and performance test in this study.It was concluded that outdoor small water quality automatic monitoring stations can provide a variety of functions including water sampling,pretreatment,multi-parameter analysis,data transmission and so on.The analysis results of different standard solutions were in high accuracy and good precision.Without any maintenance operation,the whole systems were able to run continuously and steadily for more than a week in the open air.
