Product details
YS-12 standard COD digester
1. The new type of glass burr reflux tube and heat dissipation system ensures the parallelism and accuracy of sample digestion results due to its excellent digestion reflux effect.
2. Digital display of microcrystalline panel temperature. Digital display of digestion time: temperature and timing can be set at any time.
After digestion is complete,National standard COD standard digesterAutomatically stop heating, the instrument fan continues to work for 50 minutes to assist in sample cooling, and can be left unattended.
4. Energy and water conservation, safety and reliability have improved the work efficiency of operators.
