BLA-TPN-500 Total Nitrogen Water Quality Online Analyzer

• brief introduction

The BLA-TPN-500 total nitrogen water quality online automatic analyzer is a new type of fully automatic online analyzer used to measure total nitrogen in sewage. This product is based on our patented magnetic conductivity measurement platform, combined with self-developed xenon lamp/grating spectrometer technology, digestion colorimetric integration technology, etc., to achieve high-precision, low detection limit, high stability, and low maintenance total nitrogen fully automatic online monitoring. The working principle of this product complies with the technical requirements of HJ 636-2012 "Determination of total nitrogen in water quality - Alkaline potassium persulfate digestion UV spectrophotometry", fully meeting the applications in pollution sources, industrial production processes, municipal sewage and other fields. Certified by CCEP.

• characteristic

       Magnetic conductivity measurement technology is not affected by interference such as high chromaticity, suspended solids, and bubbles;

       High reliability and strong resistance to turbidity interference;

       High detection accuracy, low quantification limit (0.1mg/L), and small long-term drift of the instrument;

       Equipped with one click self-test function and self diagnostic function;

       Single channel highly integrated valve island, capable of single valve maintenance, disassembly, and cleaning;

       Scalable 24/7 networking function, monitoring instrument operation status anytime, anywhere;

       Equipped with alarm function, quality control function, and reverse control function.

• application
