Overview
TR-701H water quality nitrate nitrogen tester is developed and designed based on the "Water Quality, Chromotropic Acid Spectrophotometry" standard. It adopts imported cold light source and narrow-band interference technology to detect sample Absorbance by Spectrophotometric method, spectra-trophotometry. The microcomputer automatically processes the data and directly displays the nitrate nitrogen concentration value (unit mg/L). The matching finished reagent makes the detection simple, fast, accurate and safe. The instrument has the characteristics of small appearance, rapid detection, simple operation and low cost. It is widely used in emergency monitoring, sewage treatment, chemical industry, wastewater, food, printing and dyeing and other industries wastewater detection, as well as R & D institutions, colleges and universities wastewater research.
