Features: 1. COD/Ammonia Nitrogen/Total Phosphorus/Total Nitrogen Quick Tester, direct reading According to national standards "HJ/399-2007 Water Quality Chemical Oxygen Demand Rapid Digestion Spectrophotometry" "HJ/535-2009 Water Quality Determination of Ammonia Nitrogen-Nessler's Reagent Spectrophotometry" "GB11893/-1989 Water quality-Determination of total phosphorus-Ammonium molybdate spectrophotometric method" "HJ636-2012 Water Quality Determination of Total Nitrogen-Alkaline Potassium Persulfate Digestion Ultraviolet Spectrophotometry" 2. Printing, data storage function Quickly print the current and stored historical data, complete the test concentration, time and other data in real time 3. Full-wavelength spectrum scanning in the ultraviolet-visible band. Full-spectrum scanning at full wavelengths satisfies the qualitative analysis of substances; supports self-built working curves to realize quantitative analysis of substances. 4. Data analysis platform The data analysis platform can achieve more precise and flexible test requirements such as spectral scanning and fixed wavelength measurement. 5. Fully automatic intelligent spectroscopic system, shining holographic grating spectroscopy, 6. The wavelength is automatically adjusted without manual operation. 7. Concave blazed holographic grating Concave diffraction gratings are different from flat diffraction gratings. They have the advantage of being able to form a spectroscopic optical system without using imaging elements such as concave mirrors. Therefore, it should be widely used in various high-end precision analytical instruments, optical communications, biology, medical equipment and other fields.
