Description

Technical Field

[0001] The utility model relates to a water detection technology, in particular to a turbidity meter with high detection accuracy. Background Art

[0002] Turbidimeter is a device for measuring the turbidity of liquid. There are scattered light type, transmitted light type and transmitted scattered light type, collectively known as optical turbidity meter. Its principle is that when light is irradiated on the liquid surface, there is a certain correlation between the ratio of incident light intensity, transmitted light intensity and scattered light intensity and the turbidity of the water sample. The turbidity of the water sample is measured by measuring the ratio of transmitted light intensity, scattered light intensity and incident light intensity or transmitted light intensity to scattered light intensity. Optical turbidity meters are used in laboratories and are also used for automatic and continuous measurement on site.

[0003] In reality, most of the turbidity meters used have probes that are carried independently. The probes are connected to the controller through wires and placed in the water sample to be tested during testing. However, the operation is not particularly convenient during use. In particular, when the turbidity of water samples is left to stand for a period of time in the testing laboratory, impurities in the water will settle to the bottom of the water, causing the data measured by the turbidity meter to be inaccurate, greatly affecting the detection accuracy.
