System overview
After the sample is filtered, it is sent to the digestion tank. At the same time, the analyzer controls the heating device for heating. Potassium melanoate is added to the digestion tank in sequence, and the concentrated sulfuric acid is digested at 100℃. The digestion time can be selected according to the raw water quality. By measuring the absorbance to convert the high Bate index concentration of the water to be measured, the system will automatically clean the entire measuring system with pure water after measurement to ensure accurate measurement next time.
Method classification
· Acid high potassium acid method: used for conventional surface water to drink groundwater;
· Alkaline high potassium acid method: used for unconventional water bodies such as seawater;
System features
· Maintenance Free Design
The water sample pre-treatment device adopts a maintenance free design, which can ensure that the maintenance cycle of the pre-treatment device exceeds six months;
· Chemical Digestion Time Can Be Adjusted
The chemical digestion time can be adjusted, and the measurement process and results meet relevant standards;
· Adjustable Quantitative Sampling Device
Ensure that the instrument accurately measures various water samples by adjusting the reagent dosage and sampling amount;
· Non Contact Injection Pump
The use of reagents adopts a non-contact injection pump to avoid direct corrosion of the reagent pump, which can extend the service life of core components and reduce user usage costs;
· All Imported Devices
The analysis of flow path design and reagent formulation ensures measurement reproducibility, with a current measurement reproducibility of up to 5%;
· Fully Automatic Operation
No need for personnel on duty, it can achieve intelligent functions such as automatic zero adjustment, automatic calibration, automatic measurement, automatic cleaning, automatic maintenance, self-protection, and automatic recovery;
