Overview
The FXJ-12W national standard COD digester is a national standard method COD reflux digester independently developed and produced by Feixiang Saisi Company. It is a practical new national standard COD digester developed and researched according to the environmental protection standard "HJ 828-2017 Determination of Chemical Oxygen Demand in Water Quality - Dichromate Method" of the People's Republic of China. It is suitable for the determination of chemical oxygen demand in surface water, domestic sewage, and industrial wastewater.
Product Details
● Standard MicrocrystallineCODThe digestion device adopts imported microcrystalline panels. The panel is durable800High temperature microcrystalline board with uniform heating on the surface and fast heating and cooling rates. The heating part uses a new imported high-temperature resistant ceramic fiber heating plate, which reduces the heat loss of the bottom plate and surrounding area of the digester, ensures uniform heating and thermal conductivity, and has higher thermal efficiency.
Microcrystalline panels are flat, smooth, and easy to clean; If the surface is stained, simply wipe it dry with a cloth to reduce damage to the instrument caused by improper operation.
The new glass burr reflux tube and heat dissipation system ensure the parallelism and accuracy of sample digestion results due to their excellent digestion reflux effect.
● Digital display of microcrystalline panel temperature, temperature range (within165℃-330Between ℃.
● Digital display of dissolution time: The dissolution time is within5minute-150Between minutes.
After digestion is completed, the instrument automatically stops heating and the instrument fan continues to work120Minute, auxiliary sample cooling, can be unattended.
● Energy saving, water-saving, safe and reliable, improving the work efficiency of operators.
