Fluoride on-line monitor adopts the national standard (GB 7483-87) water quality fluoride measurement - fluorine reagent spectrophotometric detection. This instrument is mainly used for monitoring surface water, groundwater monitoring, industrial wastewater, etc., and is mainly used for regional reference, surface and groundwater monitoring in areas with high dental caries and fluorosis. The analyzer can automatically and continuously work according to the on-site setting for long-term unattended operation, and is widely used in industrial waste water discharge, industrial process wastewater and other occasions. According to the complexity of the field test conditions, the corresponding pre-treatment system can be selected to ensure the test process is reliable and the test results are accurate, which fully meets the on-site requirements of different occasions.
产品原理：
氟离子在pH4.1的乙酸盐缓冲介质中，与氟试剂及硝酸镧生成蓝色三元络合物，颜色的强度与氟离子浓度成正比，在620nm波长处定量测定氟化物（F-）。
Product Principle: The fluoride ion forms a blue ternary complex with the fluorine reagent and cerium nitrate in the acetate buffer medium of pH 4.1. The intensity of the color is proportional to the concentration of the fluoride ion, and the fluoride is quantitatively determined at the wavelength of 620 nm (F- ).
