<p>PROBLEM TO BE SOLVED: To provide a probe capable of precisely measuring state of a fluid.SOLUTION: The probe comprises: a guide which is arranged so that the outer peripheral surface is in contact with the inner peripheral surface hole H and to protrude at the other side X of a wall W in a state being inserted in a hole H; and a probe main body disposed at the inner peripheral side of the guide and is arranged to make a relative movement with respect to the guide from one side Y to the other side X. The guide has movement regulation parts 23A, 33A and 43A for regulating end portions 23C, 33C and 43C at the other side X not to move toward the one side Y exceeding a plane W2 at the other side X of the wall W. The probe main body is arranged so that the end portion at the other side X can protrude toward the other side X exceeding the end portions 23C, 33C and 43C at the other side X of the guide.</p> |
