Title: Leaking-liquid detecting sheet
Inventor: MARUYAMA YASUYUKI
IPC: G01M3/16
Filed: 1990-09-27
Abstract: PURPOSE:To obtain a leaking-liquid detecting sheet for visual discovery, by setting a discoloration region of an acid-base indicator to include a pH region of an objective detecting liquid after electrolysis and not to include a pH region of a cleaning agent for cleaning an objective detecting area. CONSTITUTION:An electrode 2 consists of two kinds of metal wires differing in electrode potential for an objective detecting liquid, for example, saltwater. An acid-base indicator impregnated in a liquid-absorbing cloth exhibits an acid color when a pH of an objective detecting liquid after electrolysis is below a discoloration region, a basic color, i.e., the indication color, when the pH exceeds the region and a mixed color of the two when it is within the region, That is, if the objective detecting liquid is saltwater, it becomes strong alkaline reaching the coloration region after electrolysis. However, because a cleaning agent is normally weak alkaline or weak acid, not containing an electrolyte, and does not discolor, the differentiation between a corrosive objective detecting liquid and a cleaning agent can be performed by the visual confirmation.
