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, adds methyl orange indicator, and drops sulfuric acid solution for titration. During titration, the instrument's optical system can detect the change point of methyl orange solution from orange-yellow to orange-red, record the amount of sulfuric acid added at each point of change, and then systematically calculate the methyl orange alkalinity.
