Online ammonia nitrogen analyzer

The application of online ammonia nitrogen analyzer is widely used in the inlet and outlet of sewage and water plants; Water quality monitoring stations for reservoirs, water sources, surface water, lakes, and rivers. The instrument monitoring data is stable, accurate, and durable.

Product Features:

Adopting the national standard salicylic acid method, it has high accuracy and good stability;

The structural design of * * has lower failure rates, lower maintenance requirements, lower reagent consumption, and higher cost-effectiveness;

The valve components of ● * and flexible switching of multiple channels make the equipment easy to maintain and have a long service life;

The precise optical system enables accurate measurement of reagents, overcoming quantitative errors caused by wear and tear of peristaltic pumps and pump tubes, and achieving precise quantification of trace reagents, greatly reducing the amount of reagents used;

Power off data protection ensures that instrument system data is not damaged and data records are not lost;

● Multiple signal output interfaces to meet various access requirements;

● It has an over limit alarm function and can be used in conjunction with a sampler to achieve over limit sample retention;

● With network functionality, data sharing and remote control can be achieved through a network platform;

Equipped with a micro printer for easy data storage.
