Description

technical field

[0001] The invention relates to water quality measurement and control instrument technology, in particular to a temperature control device for a measuring instrument and the measuring instrument, which can be widely used in various water qualities and rapidly measure BOD value by using a microbial electrode method. Background technique

[0002] The composition of organic matter in domestic and industrial wastewater is very complex, and it is extremely difficult to determine the content of a certain component alone. However, the harm of these organic substances to the surrounding environment is mainly caused by the consumption of oxygen in the water body. Therefore, in practical applications, the oxygen consumption such as biological oxygen demand, chemical oxygen demand, and total oxygen demand is used to represent the water body. The degree of organic contamination.

[0003] Biochemical oxygen demand (BOD) is a comprehensive index indicating the content of ...
