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.
