Q46F/D Direct Fluoride Monitor

Continuous, Accurate and Reliable Fluoride Monitoring

Many drinking water systems add fluoride to their water to help their residents prevent tooth decay. To achieve a fluoride concentration of about 1 PPM, a hydro-fluorosilicic acid or sodium fluoride solution is metered into the process at a rate that is proportional to total plant flow. However, flow control problems may result in a loss of chemical feed or over-feed condition. An on-line fluoride monitor can provide reliable control of chemical addition for a consistent fluoride concentration.

The Q46F/D Fluoride Monitor provides continuous measurement of free fluoride concentration in potable water without sample conditioning. The system employs a fluoride-sensitive ion selective electrode (ISE) which provides reliable measurements down to 0.1 PPM and as high as 1000 PPM. The system is designed for use in applications where the pH and conductivity of the water are relatively stable. Fluoride measurement applications with widely varying sample conditions may require a more sophisticated system employing automated sample conditioning such as our Q46F-AutoChem system.
