Main features of online total nitrogen analyzer:

·*The design of this product enables it to have a lower failure rate, lower maintenance requirements, lower reagent consumption, and higher cost-effectiveness compared to similar products.

·Select valve component: Select reagent sampling timing sequence.

·Measurement component: Accurate measurement of reagents is achieved through a visual photoelectric system, overcoming quantitative errors caused by wear of peristaltic pump tubes; At the same time, precise quantification of trace reagents has been achieved, with each dose being only 1.5 ml, greatly reducing the amount of reagents used.

·Sample injection component: peristaltic pump negative pressure suction, there is always an air buffer zone between the reagent and the pump tube to avoid corrosion of the pump tube.

·Sealed digestion component: High temperature and high pressure digestion system accelerates the reaction process and overcomes the corrosion of equipment caused by the volatilization of corrosive gases in open systems.

·Reagent tube: using imported modified polytetrafluoroethylene transparent hose with a diameter greater than 1.5 mm, reducing the probability of particle blockage in water samples.

The online total nitrogen analyzer product is easy to measure, and the sample to be tested does not require any pre-treatment. Simply insert the water sample lifting tube directly into the system water sample to measure the total nitrogen concentration. The device has a large measurement range of 0-500mg/L TN, and this method is mainly used for online automatic monitoring of total nitrogen concentration in waste (sewage) discharge point sources, surface water, etc.
