Standard COD Dissolver (6 Cone Bottles)

KY-100 standard COD digesterUsing microelectronics technology for timed control of the heating electric furnace, it can process 6 conical bottlesMaoThe use of a needle reflux tube instead of a ball reflux tube and air cooling technology instead of tap water cooling 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:

1. Adhered to the basic principles of ISO and GB standards, ensuring a digestion operation with reflux heating and micro boiling for 2 hours.

2. The preparation and dosage of the reagent solution are consistent with the GB method * to ensure reliable and accurate analysis results.

3. Simple, accurate analysis results, water conservation, and automatic shutdown after completion.
