Product Description
Fully based on national regulations "Determination of water content of chemical oxygen demand rapid digestion spectrophotometry (HJ / T399-2007)" and "Determination of ammonia nitrogen in water quality Nessler reagent spectrophotometric method (HJ535-2009)" design and manufacture, applicable to many domestic and foreign testing standards.
Feature:
1,Rapid and accurate determination of surface water, water, urban sewage and industrial wastewater COD;
2,Simultaneous determination of ammonia nitrogen, COD high range, COD low range of water samples;
3,Independent dual optical path without interference system,the concentration of direct reading, high precision, long life,more stable;
4,Instrument-owned calibration function, according to the standard sample Calculate and store curves with-out manual production of curves;
5,Large and small font display mode free to switch, display data clearer, more detailed parameters;
6,Transfer the current data and historical data to the computer, support USB, infrared wireless transmission (optional);
7,While supporting the cuvette and colorimetric two colorimetric way;
8,The instrument has a built-in printer that prints current data and all stored historical data;:
9,Equipped with your professional supplies reagents, work steps greatly reduced, the measurement is more simple and accurate;
10,It adopts self designed anti acid, alkali and corrosion resistant shell, machine nice;
11,Support historical data storage view function, can store 12,000 data;
12,Intuitive menu navigation system and 3.5-inch color LCD screen, user-friendly operation tips, the use of more simple;
