PCM300-TP Total Phosphorus Water Quality Online Automatic Monitor

Principle

The principle of ammonium molybdate spectrophotometry is to digest the sample with potassium persulfate and convert all the phosphorus contained into orthophosphate. In an acidic medium, orthophosphate reacts with ammonium molybdate to form phosphomolybdate heteropoly acid in the presence of antimony salt, which is immediately reduced by ascorbic acid to produce a blue complex whose absorbance is proportional to the concentration of total phosphorus.

Main 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 with 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;

Typical application

l  Online monitoring of total phosphorus in drinking water and surface water;
