1、 Working principle:
DS-TN200C Total Nitrogen AnalyzerUsing ultraviolet light to pass through the test sample, according to Lambert Beer's law, the concentration of total nitrogen in the sample (mg/L) is calculated by measuring the absorbance value. Using imported high-performance, long-life, and high brightness light sources, coupled with a highly stable optical system, with good precision and repeatability; Capable of printing and uploading USB data; This instrument is widely used in environmental monitoring, sewage treatment, colleges, research institutions and other departments.
