PCM300-TN Total Nitrogen Water Quality Online Automatic Monitor

We are pleased to introduce our PCM300‑TN Total Nitrate Water Quality Online Automatic Monitor, a high‑performance solution for accurate and stable online water quality monitoring.

TN Total  Nitrate Water Quality Online Automatic Monitor Principle

After potassium sulfate oxidation, ultraviolet spectrophotometry

In the presence of potassium persulfate, the nitrogen-containing compounds in the  water sample are fully oxidized and digested to oxidize the nitrogen-containing compounds in the water sample to nitrate ions, and then the absorbance measured by ultraviolet spectrophotometry is used to calculate the total nitrogen content.

Features

l  Ten-port valve with sapphire core, high wear resistance, strong acid and alkali resistance, organic solvent resistance, strong service life and high stability;

l  The syringe pump is used for precise quantification, and the water sample and reagent are more stable and accurate to ensure the measurement accuracy.

l  Using a specially designed reference method, the slight displacement of the digestion tank and the slight pollution of the digestion tank will not affect the measured value;

l  With waste liquid separation function, to achieve the separation of high-concentration reaction waste liquid and low-concentration cleaning waste liquid;

l  With automatic dilution function, can automatically adjust the range file according to the actual water quality on site;

l  Built-in quality control functions such as standard recovery, zero point verification, standard sample verification, parallel sample test, etc., and it can be started automatically, manually, remotely, etc.;

l  With automatic fault diagnosis and abnormal information upload and recording functions, such as parts failure, over-range alarm, over-standard alarm, lack of reagent alarm and other information;

l  With overheating protection: the heating temperature is too high, the heater is automatically powered off;

l  After abnormal reset and power failure, the instrument automatically discharges the residual reactants in the instrument and automatically restores to the original working state. With power-on alarm function, the instrument will generate alarm information when power is turned on again after power-off;

l  With analysis instrument process log and measurement data recording and alarm information storage function, data calculation is recorded once every hour, can be stored for 3 years, and U disk can quickly export data;

l  With three-level management authority;

Application

l  Online monitoring of total nitrogen concentration in drinking water and surface water;

l  Online monitoring of total nitrogen concentration in municipal sewage inlet and outlet, pollution source discharge outlet, and industrial wastewater outlet.
