TEM on-line ammonia nitrogen analyzer (Nessler's reagent method)

● Water inlets and outlets of sewage plants and waterworks ● Sewage outlets of various enterprises

After the water sample and the masking agent are mixed, the ammonia nitrogen in the form of free ammonia or ammonium ions reacts with Nessler's reagent to form a colored complex. The analyzer detects this color change and converts this change into The ammonia nitrogen value is output. The amount of colored complexes produced corresponds to the amount of ammonia nitrogen.

● Adopting Nessler's reagent colorimetric method, with high accuracy and good stability;
● Unique structural design, with lower failure rate, lower maintenance, lower reagent consumption and higher cost performance;

● Unique valve assembly and flexible switching of multiple channels, which makes the equipment easy to maintain and have a long life.
● The precise optical system realizes the precise measurement of reagents, overcomes the quantitative error caused by the wear of peristaltic pumps and pump tubes, and achieves the accurate quantification of trace reagents, greatly reducing the amount of reagents used
● Power-off data protection to ensure that the instrument system data is not damaged and data records are not lost;
● Multiple signal output interfaces to meet different access requirements;
● It has the alarm function of exceeding the standard, which can be used in conjunction with the sampler to achieve sample retention beyond the standard;
● With network function, data sharing and remote control can be realized through the network platform;
● Equipped with a micro printer, which is convenient for permanent data storage.
