● The water inlet and the water outlet of sewage treatment plant and tap water factory
● Sewage outfall of each enterprise
● Lake and river water quality monitoring statio
Mixedwater and masking agent, ammonia nitrogen with free ammonia or ammonium ionform, reaction with Nessler's reagent to form a colored complex, change thecolor of the analyzer, and the change of output value is converted to ammonianitrogen. The amount of color complex is equivalent to the amount of ammonianitrogen.
● The reagent colorimetric method is adopted, which has high precision and good stability;
● Unique structural design with lower failure rate, lower maintenance, lower reagent consumption and higher cost performance;
● A unique valve assembly, multiple channel flexible switch, the equipment has the advantages of easy maintenance, long service life etc.;
● Optical system to achieve precise accurate measurement of reagent peristaltic pump, pump, overcome due to quantitative error caused by abrasion, while achieving a precise quantitative trace reagent, greatly reducing the using amount of reagent;
● Power down data protection to ensure that the instrument system data is not damaged and the data record will not be lost;
● A variety of signal output interface to meet a variety of access requirements;
● Have exceed the standard alarm function, and with the use of samplers, can exceed the standard sample;
● With network functions, through the network platform, data sharing and remote control can be achieved;
● Equipped with a micro printer to facilitate data permanent preservation
