Product Overview:

HACH 5500SC AMC Ammonia/Monochloramine Analyzer HACH is an intelligent monitoring solution designed specifically for chloramine disinfection processes. This instrument accurately measures the concentrations of total ammonia, free ammonia, and monochloramine, effectively preventing nitrification reactions and odor issues, providing reliable data support for the stable operation of water treatment processes, and helping to achieve safe and efficient disinfection management.

Working Principle:

The 5500sc AMC uses an improved phenolic salt colorimetric method, ensuring data accuracy through two-stage measurement:

• Chloramine concentration determination

  Phenolic salt analysis is performed directly on water samples to obtain the initial concentration value of monochloramine.

• Total ammonia concentration conversion measurement

  Additionally, water samples were taken and excess hypochlorite added. Under specific pH conditions, all free ammonia was converted into monochloramine, and the total ammonia concentration was measured again by phenolic salt method.

• Free ammonia calculation

  By subtracting the chloramine concentration from the total ammonia concentration, the free ammonia content undisturbed by residual chlorine can be accurately determined.

Instrument Features:

● The 5500SC AMC uses the colorimetric method for measurement, greatly improving reliability over traditional products and achieving a good unity between accurate measurement and low maintenance

● Avoid nitrification reactions, odors, and the generation of unpleasant odors

● Significantly reduces equipment maintenance requirements

● Provides simple fault diagnosis instructions to guide customers in operation

Application Areas:

Suitable for chloramine disinfection processes in tap water, monitoring total ammonia, free ammonia, and monochloramine content.
