#BODG-3063 ONLINE BOD ANALYZER

The BODG-3063 Online BOD analyzer produced by BOQU Instrument.it’s widely used in industrial, electric power, agriculture, medicine, food, scientific research and environmental protection. The instrument is also an essential inspection equipment in the food factory, drinking water factory QS, HACCP certification.BOD(Biochemical Oxygen Demand) is an environmental monitoring indicator used to monitor the pollution of organic matter in water. Generally, organic matter can be decomposed by microorganisms, but microorganisms need to consume oxygen when decomposing organic compounds in water. If the dissolved oxygen in the water is insufficient to supply microorganisms, the water is in a state of pollution. BOD is an indicator of environmental protection.

Principle:
The mixed liquid of Water sample, potassium dichromate solution, mercury sulfate , silver sulfate solution is heated upt to 165 ° C. The color of the organic substance in the dichromate ion oxidizing solution changes. The BODG-3063 online BOD analyzer detects the change in the color and converts the change into BOD value.The amount of dichromate ions consumed is equivalent to the amount of oxidizable organic matter.
