The invention provides a tunnel monitoring measuring device for aiming at a tunnel dark environment and a configuration method. The device comprises a transparent housing. The transparent housing is internally provided with light emitting diodes which are distributed in a matrix manner. The housing is provided with a cross wire at a position which corresponds with the distribution area of the light emitting diodes. Furthermore the center of the cross wire is at the center of the matrix of the light emitting diodes. The housing is provided with a locking mechanism. The measuring device can be fixed to the measuring point position. Through the transparent device, inner light can be diffused to outside through the housing, and easy finding in a dark environment is realized, thereby realizingno requirement for additional labor force for illumination for searching the measuring point.
