PCM300-NH3N
PROBEST
Measurement Principle:
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.
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 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;
Applications:
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.
