NPW-160 Total Phosphorus / Total Nitrogen / COD Analyzer

image/y2011712161156
Product description
Technical indicators
- working principle:
 
Total phosphorus (according to international GB11893-89): Add potassium persulfate as oxidant to the sample, digest the water sample to be tested at 120 ℃ for 30min, convert the phosphide into phosphate ion, and use the molybdenum blue method to absorb water to detect the water quality The total phosphorus content (measurement wavelength: 700nm)
 
Total nitrogen and potassium persulfate are used as oxidants (according to international GB11893-89): potassium persulfate is used as oxidizer and digested at 120 ° C for 30 minutes to convert the nitrogen-containing compounds into nitrate ions and adjust the pH of the sample solution to 2- 3; The content of total nitrogen in water quality is detected by ultraviolet absorption spectrophotometry (measurement wavelength: 220nm, 275nm turbidity correction: A = A220-A275 × 2)
 
COD (UV): dual-wavelength absorbance photometry (UV 254nm, visible light 546nm)
 
 
 
-Application industry:
 
The NPW-160 total phosphorus / total nitrogen analyzer is mainly used for automatic monitoring of total phosphorus, total nitrogen and COD in surface water, tap water, municipal sewage or other special occasions.
 
 
 
-Instrument features:
 
● Independently designed heating decomposition device
 
● The system can realize wireless transmission
 
● Built-in CF card, data can be stored for a long time
 
● Low operating cost and less secondary pollution
 
● Integrated design simplifies pipeline connection
 
● Advanced multi-wavelength detector can measure three indicators: total phosphorus, total nitrogen, COD (UV)
 
 
 
- Product advantages:
 
● Built-in multi-wavelength detector, one measurement can get two parameters at the same time, including total nitrogen and total phosphorus;
 
● According to JIS standard (heating at 120 oC for 30 min), the same measurement method is adopted; it has good accuracy and stability;
 
● Low operating cost, reduce reagent consumption and waste liquid discharge;
 
● Built-in multiple functions, data storage card (can save one year of measurement data), reagent quantitative sampling system;
 
● Can be equipped with wireless transmission function.
