1、 Product Introduction:

※TC-100EType standardCOD（cr）The measuring instrument follows international standards（ISO）In accordance with national standards（GB）The basic principle ensures reflux heating with slight boiling2The digestion operation for hours, the preparation and addition of reagent solution are all in accordance withGBLaw consistency ensures reliable and accurate analysis results.

※ standardCODThe digestion device adopts microcomputer technology for timed control of far-infrared electric furnace plates, which can8One12Simultaneously heating the digestion reflux device. To achieve the goals of energy conservation, reducing power load, and improving efficiency.

The instrument adopts a glass burr reflux tube instead of a spherical reflux tube, and uses air cooling technology instead of tap water cooling, which can not only save water and standardize the instrument, but also improve the safety of instrument use.

※ standardCODChemical solution preparation, operation andCODThe calculation is completely in accordance withGB11914—89, lower than50mg/LofCODThe accuracy of water samples can be improved by diluting titrants and oxidants, which is higher than1000mg/LofCODWater samples can be measured by diluting them proportionally.

※ national standardGB11914—89Standardized analytical methods have been developed to determine the chemical oxygen demand for water qualityCOD（cr）The measurement steps strictly specify the conditions and indicators of the method, such as heating and digestion time, solution acidity, oxidant and catalyst dosage. It is obvious that the water qualityCOD（cr）There are strict conditions for the measurement, and any operation that violates these conditions will affect the accuracy of the measurement.
