Hach Hash AmtaxTM inter2 Ammonia Nitrogen Online Analyzer

Typical applications
Used for online monitoring of ammonia nitrogen concentration in drinking water and surface water.

Instrument characteristics
Measurement of NH4 in water using a dual beam and dual filter photometer⁺Ionic concentration. By measuring the reference beam, the instrument eliminates the interference of factors such as turbidity and power supply fluctuations in the sample on the measurement results.
The measured values can be displayed in graphical or numerical form.
● It has functions such as automatic calibration and automatic cleaning.
● Built in refrigerator to ensure the storage temperature of reagents
Use the FILTRAX sampling preprocessing system for sample preprocessing.
● Data storage function, graphic display function

Detection principle:
Indigo phenol blue method (compliant with DIN 38406 E5 standard). Under the action of the catalyst, NH₄⁺In an alkaline medium with a pH of 12.6, it reacts with hypochlorite ions and salicylate ions to form indophenol compounds, which appear green. Within the measurement range of the instrument, the degree of color change and NH in the sample₄⁺The concentration is proportional, therefore, by measuring the degree of color change, NH in the sample can be calculated₄⁺The concentration.
