Water Fluoride Detector

I. Product Overview

The water quality fluoride analyser is a professional instrument developed on the basis of fluoride reagent spectrophotometry and designed for the rapid, accurate assessment of water safety.
Fluoride is a two-sided indicator for health and safety: an appropriate amount in drinking water benefits the teeth, but an excess causes dental fluorosis and skeletal fluorosis, harms the ecological environment and corrodes industrial equipment. By measuring the absorbance of a water sample after colour development with a dedicated reagent and calculating the concentration automatically from the built-in standard curve, the instrument clearly distinguishes safe from harmful levels.
The instrument integrates a complex laboratory analysis procedure into a single housing and is simple to operate. Its performance meets the requirements of the national standard method, making it suitable for drinking water safety screening, environmental water body patrols, industrial wastewater discharge monitoring and emergency testing.

II. Measuring Principle

The instrument uses fluoride reagent spectrophotometry (the national standard method). Under a specific acidity the fluoride ions in the sample react with the fluoride reagent and lanthanum nitrate to form a stable blue ternary complex whose colour depth is proportional to the fluoride concentration. The precision optical system measures the absorbance of the solution at a specific wavelength and calculates the fluoride concentration (mg/L) directly from the preset calibration curve. The method offers strong interference resistance and accurate, reliable results.

III. Applications

The instrument is a professional tool for the rapid determination of fluoride in water, serving environmental monitoring, industrial self-inspection, public health protection, research and emergency response. It helps environmental inspectors screen samples from rivers, lakes and drinking water sources; supports quality control staff in electrolytic aluminium, semiconductor and electroplating plants in rapid compliance self-checks of process water and wastewater outfalls; assists disease control centres and water plant staff in assessing fluoride safety in network terminal water and rural drinking water; and provides immediate data support for field geological surveys and emergency monitoring of sudden water quality incidents.
