The F-1 fluoride ion concentration meter is an electrochemical analysis instrument that uses direct potentiometry to accurately measure the fluoride ion concentration in a solution. The instrument can not only measure the concentration of fluoride ions in aqueous solutions, but also serve as a rapid measure for the chemical defense of troops against phosphorus containing toxins, sarin, and soman.
