METAL CYLINDER RESISTANCE MEASUREMENT JIG, RESISTANCE MEASUREMENT SYSTEM, RESISTANCE MEASUREMENT METHOD, AND PLATE THICKNESS EVALUATION METHOD

To provide a resistance measurement jig, a resistance measurement system, a resistance measurement method, and a plate thickness evaluation method, which can easily evaluate the plate thickness even when a metal cylinder is corroded.SOLUTION: A resistance measurement jig 3 includes a plate-shaped main body 3A that can be deformed to match the shape of a metal cylinder, and multiple drill blades 34 extending in a direction that intersects a plate surface direction of the main body 3A, and rotatably supported in a state aligning in a line in the plate surface direction of the main body 3A. The drill blade 34 is configured to be connectable to a terminal of a resistance meter, and may have conductivity capable of conducting electrical signals. A magnet 31 that attracts the surface of the metal cylinder may be provided on the bottom surface of the main body 3A.SELECTED DRAWING: Figure 4 【課題】金属筒体が腐食している場合でも板厚を簡単に評価できる抵抗測定治具、抵抗測定システム、抵抗測定方法及び板厚評価方法を提供する。【解決手段】抵抗測定治具３は、金属筒体の形状に合わせて変形可能な板状の本体３Ａと、本体３Ａの板面方向に交差する方向に延び、本体３Ａの板面方向に一列に並べた状態で回転可能に支持され、金属筒体に形成された錆皮膜を除去可能な複数のドリル刃３４と、を備える。ドリル刃３４は、抵抗計の端子を接続可能に構成され、電気信号を導通可能な導電性を有してもよい。本体３Ａの底面部には、金属筒体の表面に吸着する磁石３１が設けられてもよい。【選択図】図４
