Analytical Technology (ATi) has developed an innovative new Fluoride Monitor to provide reliable and continuous measurements of free fluoride concentration in potable water Employing a fluoride sensitive ion selective electrode (ISE) sensor, the novel ATi A15/82 Fluoride Monitor provides dependable measurements of fluoride down to 0.1 PPM and as high as 1000 PPM

A chemistry module offers sample conditioning for the sensor while the measured fluoride concentration is displayed on a separate electronics module that has been equipped with alarm and analogue output functions.
Fluoride is widely added to drinking water systems to help prevent tooth decay.
Optimum fluoride levels of around 1 PPM are safe for human health, but concentrations above 2 PPM are considered excessive and need to be detected as early as possible.
Therefore, monitoring of final fluoride concentration is absolutely essential in order to identify any overfeed problems.
Loss of chemical feed can also be detected quickly and reliably with on-line fluoride monitoring.
The new ATi A15/82 Fluoride Monitor is particularly simple in operation.
A small amount of sample is pumped into the system and mixed with the buffer solution.
The treated sample then flows to a chamber where the combination fluoride ISE is mounted.
The continuous flow of sample is measured in this chamber with changes in fluoride concentration immediately reflected at the monitor.
The sample chamber drains back to the waste side of the sample inlet overflow chamber.
The groundbreaking A15/82 Fluoride Monitor requires only very little maintenance whilst one gallon of buffer operates the system for approximately 45 days.
Additionally, the system performs an automatic calibration routine to correct for electrode "zero" drift.
The fluoride standard is automatically pumped into the chemistry module and the analyser zero is automatically adjusted.
The frequency of this calibration is user-selectable from every 1 to 999 hours.
Calibration standards are easily mixed from a stock solution provided with the unit and the buffer is prepared using common vinegar. Request a free brochure from Analytical Technology ...
