This product uses N-(1-naphthyl)ethylenediamine dihydrochloride spectrophotometry to detect nitrite nitrogen. The nitrite in the water sample reacts with N-(1-naphthyl)ethylenediamine dihydrochloride to form a purple-red complex at 40°C. The color depth of the solution is proportional to the nitrite nitrogen content in the sample. The instrument determines the nitrite nitrogen of the water sample through photoelectric colorimetry.
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.
