Water Online monitoring of ammonia and nitrogen concentrations in drinking water and surface water;
Municipal sewage import and export, pollution source discharge, and industrial nitrogen wastewater ammonia nitrogen concentration online monitoring.
The instrument adopts salicylic acid optical colorimetry, the sample and the color reagent are sent to the salicylic acid optical colorimetric LED photometer for clearing measurement; the sample and the color reagent are fully mixed and chemical reaction occurs under the action of air , According to the color change of the developer, finally calculate the ammonia nitrogen concentration value.
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 With good 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;
l Water Online monitoring of ammonia and nitrogen concentrations in drinking water and surface water;
l Municipal sewage import and export, pollution source discharge, and industrial nitrogen wastewater ammonia nitrogen concentration online monitoring.
