PURPOSE:To detect the liquid leakage of a container with high efficiency by charging liquid-tight container with a liquid wherein gas is dissolved, and by detecting its leakage gas under conditions where the dissolved gas evaporates from the liquid when the liquid leaks out of the container. CONSTITUTION:Fluorocarbon gas, e.g., R-12 is applied with 4kg/cm to be dissolved in oil. Oil 10 containing this R-12 with high density is applied with prescribed test pressure from the connection openings 3 and 4 of a hydraulic cylinder 1. In this state, the detection part 21 of a halogen leak detector checks the external circumferential surface of the hydraulic cylinder 1. If the oil leaks from the stroke end part 5 of the cylinder, the leakage oil 10 is decreased in pressure to the atmospheric pressure, so the probe gas R-12 is discharged from the oil by the Henry's law and collected by the detection part 21 to make an indication by a measurement part, thus finding the liquid-leakage position efficiently. |
