Product Overview:

HACH has upgraded and developed a new generation of online ammonia nitrogen monitoring product—the Amtax NA8000 Ammonia Nitrogen Detector—to meet the demand for ammonia nitrogen detectors in the Chinese market. The Amtax NA8000 online ammonia nitrogen detector uses the salicylic acid-indphenol blue method, improving measurement accuracy, stability, and maintenance. This ammonia nitrogen detector adopts a dual-wavelength and dual-path cuvette design, with four ranges that can automatically switch, automatically calibrate, and clean, while also supporting data storage and graphical display to meet various needs of water quality ammonia nitrogen detectors.

Working Principle:

The Amtax NA8000 ammonia nitrogen detector uses the salicylic acid–indophenol blue method to determine ammonia nitrogen concentration. Due to the action of the catalyst, NH4+ reacts with hypochlorite ions and salicylate ions in an alkaline medium to form indophenol compounds, which appear green. Within the measurement range of the ammonia nitrogen detector, the degree of color change is proportional to the concentration of NH4+ in the sample. The Amtax NA8000 ammonia nitrogen online monitor calculates the concentration of NH4+ in the sample by measuring the degree of color change, thereby enabling online ammonia nitrogen monitoring.

Instrument Features:

● Uses a dual-wavelength and dual-path cuvette design, using reference beam measurements to eliminate interference from sample turbidity, power fluctuations, and other factors affecting online ammonia nitrogen monitoring results, ensuring measurement accuracy.

● Offers multiple fixed range options, with automatic range switching, high flexibility, and adaptability to ammonia nitrogen detection needs under different water quality conditions.

● Uses CYQ-type water sample preprocessors for sample preprocessing to ensure the accuracy of sample testing.

● Equipped with Hax's advanced Prognosys pre-diagnostic technology, providing preventive maintenance reminders and reducing the risk of downtime for online ammonia nitrogen monitors.

● Equipped with Diagnose self-diagnosis function, it can automatically diagnose instrument status, display diagnostic results on the screen, query diagnostic information, and output via digital interface.

● Flexible configuration of multi-channel multi-module input/output modules to meet complex water quality monitoring needs.

● Features automatic calibration and automatic cleaning, requiring low maintenance.

● Supports data storage and graphical display functions.

● Reagents can be stored and used at room temperature for convenient daily operation.

● Supports both Chinese and English interfaces, making historical data display more user-friendly.
