► PRODUCT INTRODUCTION The main purpose of the total nitrogen online automatic analyzer is to monitor nitrogen-containing compounds in various forms in water. In natural water and wastewater, nitrogen almost exists in the form of various nitrates, which are divided into nitrate nitrogen, nitrite nitrogen, ammonia nitrogen, and organic nitrogen (proteins, amino acids, etc.). They exist in the water environment and are the main indicators of eutrophication of water bodies. The total nitrogen automatic monitoring device is widely used in areas such as pollution monitoring points, surface water monitoring stations, river sections, and drinking water source monitoring stations. 1. The ten way valve with sapphire core has high wear resistance, strong acid and alkali resistance, organic solvent resistance, strong service life, and high stability; 2. Using a specially designed reference method, mild displacement and contamination of the digestion tank do not affect the measured values; 3. it has a waste liquid separation function, which enables the separate discharge of high concentration reaction waste liquid and low concentration cleaning solution, 4. It has a dynamic dilution function and can automatically adjust the release factor according to the range set on site: 5. It has built-in quality control functions such as spiked recovery, blank testing, standard sample verification, zero point verification, span verification, parallel sample testing, etc., and can be activated automatically, manually, and in close proximity; 6. Equipped with automaticfault diagnosis and abnormal information uploading and recording functions, such as component failure, over range alarm, over limit alarm, reagent shortage alarm, etc; 7. Equipped with overheat protection: If the heating temperature is too high, the heater will automatically shut down; 8. After abnormal reset and power failure, the instrument will automatically discharge residual reactants and return to its initial working state. Equipped with power on alarm function, the instrument will generate alarm information when powered on again after power failure, 9. It has the function of analyzing instrument process logs, recording measurement data, and storing alarm information. It records data calculation once per hour and can be stored for more than 3 years. It can also be quickly imported from a USB flash drive Provide data;
