Description

Technical Field

[0001] The utility model relates to the technical field of sewage monitoring, in particular to a turbidity meter used for sewage monitoring. Background Art

[0002] Turbidity, or the cloudiness of water, is caused by trace amounts of insoluble suspended matter and colloids in the water. Turbidity is the degree to which suspended matter in water hinders the passage of light. Suspended matter and colloids such as soil, dust, fine organic matter, zooplankton, and other microorganisms in water can cause turbidity in the water. The measurement unit used in the ISO standard is FTU, which is consistent with NTU. Turbidimeters measure water turbidity based on this principle. Turbidimeters, also known as nephelometers, can be used to test the turbidity of water samples in water plants, power plants, industrial and mining enterprises, laboratories, and in the field. This instrument is often used as an essential testing equipment for drinking water plants to obtain QS certification.

[0003] When using existing portable turbidity meters for sewage monitoring, usually only the water sample storage tube being tested can be placed on the detector, while there is nowhere to place the water classification storage tubes to be tested, which easily leads to confusion of the water samples to be tested, making the turbidity meter inconvenient to use.
