Description

Technical Field

[0001] The utility model relates to the technical field of liquid detection, in particular to a liquid transparency detection device. Background Art

[0002] The physical indicators for evaluating liquids include: temperature, color, odor, turbidity, transparency, etc. Transparency refers to the degree to which a liquid can allow light to pass through. It is a commonly used indicator for reflecting liquids. The most commonly used liquid is water, especially for water quality testing and evaluation. The water quality transparency testing methods commonly used in industrial production are mainly the lead type method and the Secchi disk method. The lead type method is to pour a uniformly mixed water sample into the transparency meter tube. The tester observes vertically downward from the mouth of the tube until the height of the water sample at which the standard lead type printed symbols at the bottom can be just seen is the transparency.

[0003] The lead type method is currently a commonly used test method for the transparency determination of natural water and lightly polluted water. It is a widely used water quality transparency test method. When testing the transparency of water quality, the sample liquid is fully shaken and injected into the volume cylinder to the highest scale, and then the liquid in the cylinder is slowly discharged from the drain until the tester can just clearly identify the standard words at the bottom. The height of the liquid level at this time is the transparency of the liquid. However, this method requires adding or draining the sample liquid multiple times during the test, which will cause the liquid environment in the cylinder to be unstable, resulting in large errors in the test results.
