Standard COD Dissolver (5 Cone Bottles)

KY-100 standard COD digesterBy using microelectronics technology for timed control of heating electric furnaces, it is possible to5 or 6A conical bottle（8. 10 or 12 column bottle)The burr reflux tube replaces the ball reflux tube, and the air cooling technology replaces the tap water cooling method, which can save water and standardize the instrument. They can maintain the necessary high temperature for the reaction within the set time to ensure digestion. It can be widely applied in fields such as environmental protection, scientific research monitoring, and production monitoring.

Main features of the instrument:

• Adhered to the basic principles of ISO and GB standards, ensuring a digestion operation with reflux heating and micro boiling for 2 hours
• The preparation and dosage of the reagent solution are consistent with the GB method * to ensure reliable and accurate analysis results
• Simple, accurate analysis results, water conservation, automatic shutdown after completion

Instrument execution standard:

• HJ828-2017 Determination of Chemical Oxygen Demand for Water Quality - Dichromate Method (Alternative to GB11914-89)
