Title: Method and apparatus for detecting leaks
Inventor: LEE DONG WOO
IPC: G01N21/78
Filed: 2020-07-06
Abstract: The present invention relates to a leak detection method employing a new concept of discoloration mechanism in which variations of colors can be clearly distinguished. In the method of detecting a leak of a detection target, as a first substance dissolved in the detection target and a second substance having a color changed in reaction to the first substance are used, when the first substance dissolved in the leaked detection target arrives at the second substance, the color change of the second substance can be detected. In accordance with the present invention, since an indicator which is discolored in reaction to a leak detection target substance is not used, there can be an effect of constituting a discoloration mechanism such that variations of colors can be more clearly distinguished. Moreover, since a chroma change can be clearly manifested, there can be an effect of enabling a person to easily check whether discoloration occurs, as well as automatically detecting discoloration by using CCD.
