Product Introduction
The working principle of the methyl orange alkalinity online monitor is based on the national standard titration method. The instrument automatically draws a certain amount of water sample, adds methyl orange indicator, and titrates with sulfuric acid solution. During the titration process, the optical system of the instrument can detect the transition point where the methyl orange solution changes from orange-yellow to orange-red, records the corresponding amount of sulfuric acid solution added at the transition point, and then the system calculates the methyl orange alkalinity.
