DEK-2027 Total Cadmium Online Water Quality Analyzer

（1）Working principle:DEK-2027The measurement method of the total cadmium online water quality analyzer is to use the dithizone spectrophotometric methodGB7471-87The pre treated water sample first reacts with an acidic oxidant in the digestion tank, reducing all forms of cadmium in the water sample to divalent cadmium, and then adjusting the solutionPHMake it highly alkaline, form a red complex with dithizone, and finally add a characteristic color reagent for extraction and color reaction518nmMeasure the absorbance of the absorption solution, and within the measurement range, the degree of color change is proportional to the total cadmium concentration in the water sample. By measuring the degree of color change, the total cadmium content in the water sample can be calculated.

（2）DEK-2027The Type Total Cadmium Online Water Quality Analyzer has the following basic functions:

－Can set and verify display time, including year, month, day, hour, and minute;

－It has an alarm function and displays the fault content in case of system abnormalities such as equipment power failure, instrument leakage, and inability to import samples into the reactor. Simultaneously stop running until the system is restarted;

－After each measurement, the equipment, instrument pipelines, valves, and other components are automatically cleaned and processed;

－Automatic protection for power and water outages, as well as automatic recovery for incoming and outgoing power;

－Regular cleaning and sampling functions;

－Touchscreen viewing is more intuitive and easier to operate;
