Product Model: NCL900
System Overview
The NCL900 on-line chlorine ammonia analyzer in water is an automatic on-line analyzer controlled by an embedded system, which can be widely used in on-line real-time water quality monitoring products for disinfectant addition control in drinking water purification process. The sample is pumped into the reactor, the interference is eliminated by catalysis and masking, and then the pH value of the solution is adjusted to make the solution have a suitable pH, and then the characteristic color developer is added to react with chlorine ammonia in water for color development, and the absorbance of the reactants is measured. The concentration of chloramine in the sample is calculated by the absorbance value and the correction equation stored by the monitor.
