Product details

Product Overview:

Ammonia nitrogen refers to the nitrogen present in water in the form of free ammonia (NH3) and ammonium ions (NH4+).

The WTF2000-NH4+ammonia nitrogen online water quality analyzer adopts the ammonia sensing electrode method, with a detection range standard of 0-1000mg/L, and can be diluted and expanded according to the actual water sample. Compared with the Nessler reagent photometric method and the salicylic acid photometric method, the ammonia sensitive electrode method has the characteristics of wide range, simple structure, and safety and environmental protection.

Product features:

Using well-known brand composite electrodes as sensors and providing electrode maintenance and replacement services;

The cost of consumables used for analysis is low, only auxiliary reagents are required, and the adaptability to water sample conditions is high;

Specially suitable for sewage detection, with a wide detection range;

Running dynamic visualization, intuitive and convenient;

Over range upper and lower limit alarm, fault alarm;

Remote reading and writing of data, supporting remote calibration and correction;

The software adopts graded password management to ensure safe use;

The instrument is equipped with automatic cleaning and calibration functions;

Reserve external interfaces and customize extension functions according to on-site conditions;
