1、 Product Introduction:

※TC-100CType standardCODThe digester 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.

※TC-100CType standardCODThe digestion device adopts microcomputer technology for timed control of the heating electric furnace, which can5Customized6One (standard)10A customized digestion conical reflux device is used for simultaneous heating. To achieve the goals of energy conservation, reducing power load, water conservation, and improving efficiency. At the same time, glass burr reflux pipes are used instead of spherical reflux pipes, and air cooling technology is used 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 of values is completely in accordance withGB11914-89，CODValue below50mg/LThe accuracy of water samples can be improved by diluting titrants and oxidants, higher than1000mg/LofCODWater samples can be measured by diluting them proportionally.

※ 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 such as heating and digestion time, solution acidity, and oxidant dosage for the method. 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.

2、 Technical features:

1The surface of the instrument is coated with a new type of corrosion-resistant paint, which is corrosion-resistant and increases its service life

2Using a conical flask for heating and digestion, it can be directly titrated after digestion without the need for switching, reducing measurement errors
