This product uses ultraviolet spectrophotometry to determine nitrate nitrogen, using the absorption of nitrate ions at a wavelength of 220nm to determine nitrate. The concentration of nitrate nitrogen in the water sample is obtained by removing dissolved organic matter through the difference in absorbance at 220nm and 275nm.
The sensor has self-diagnosis function.
The sensor has photoelectric self-balancing function automatic compensation function.
Water sample is digested closed in high temperature and pressure, with high efficiency.
The instrument is not interfered by turbidity and chromaticity of the water sample in analysis.
The instrument has many functions, including standard sample verification, zero point verification, span verification, zero point calibration, standard sample calibration, automatic calibration of working curve, and automatic test of spike recovery rate.
The instrument can be controlled remotely.
The instrument has automatic fault alarm function, such as component failure alarm, over-range alarm, abnormal data alarm, reagent shortage alarm (water sample, distilled water, reagent), and can record and upload these faults.
The instrument has the function of detecting the self-balancing of the optical path.
The instrument adopts an embedded operating system and runs efficiently.
It can be applied to surface water, groundwater, seawater, drinking water sources, pollution sources, industrial wastewater, domestic sewage and other water monitoring.
