全自动高精度氟离子快速检测仪

摘要

In accordance with the requirements of rapid Fluoride ion detection in wild field for investigation of hydraulic engineering and environmental geology, the rapid fluoride ion detector is developed by adopting Fl-ion selective electrode and based on the least square method ( LSM) . The design of hardware and software of the instrument and the curve fitting method are described in detail. The test results show that the relative error is ≤5%, and the instrument features low power consumption, high integration, and high accuracy, it is particularly suitable for rapid detection of Fl-ion in water in field site survey.%针对水工环和水资源调查野外氟离子快速检测的需求，利用氟离子选择性电极，基于最小二乘法(LSM)，研制了氟离子快速检测仪。详细阐述了仪器的硬件和软件设计、曲线拟合方法等。测试结果表明，仪器检测相对误差≤5%，具备低功耗、高集成度、高精度等优点，特别适合于野外现场水中氟离子的快速检测，具有广阔的应用前景。
