WXZJ-N20A Total Nitrogen Online Analyzer Applications:

    Used for online automatic continuous analysis and detection of total nitrogen in industrial wastewater, surface water, drinking water, seawater, and industrial process control.

Instrument Features:

l Humanized design, making this product have lower failure rate, lower maintenance, longer service life, higher cost performance, and higher accuracy compared to similar products;

l Uses original imported selection valves with long service life, easy installation, and convenient maintenance and replacement;

l Achieves precise reagent measurement through a visual photoelectric control system, overcoming quantitative errors caused by wear of peristaltic pump tubes;

l The peristaltic pump adopts a negative pressure suction method, always maintaining an air buffer between the reagent and the pump tube, avoiding corrosion of the pump tube and hardware corrosion in case of pump tube rupture;

l Uses imported modified PTFE transparent soft tubes with a diameter greater than 1.6mm, reducing the impact of sample particle blockage on system measurement;

l Uses an original imported solenoid valve to form a high-temperature and high-pressure digestion system, ensuring the system is safer and more reliable, thus making the reaction of the measured substances in the sample more complete and thorough;

l Uses imported temperature measurement components to form a precise temperature control system, and adopts temperature compensation technology to overcome the effects of temperature drift, ensuring the sample reaction conditions better meet requirements;

l Uses original imported light sources from the United States, greatly improving the instrument's measurement accuracy and detection limit.
