The utility model relates to an on-line carbon fiber stability monitoring device. The device comprises a bracket, a power supply, a measuring instrument, a positive electrode roller and a negative electrode roller, wherein the positive electrode roller and the negative electrode roller are fixed on the bracket and are arranged sequentially along a running direction of carbon fibers; the positive electrode roller is connected with a positive electrode of the power supply; the negative electrode roller is connected with a negative electrode of the power supply; insulating materials are respectively arranged between the positive electrode roller and the bracket and between the negative electrode roller and the bracket; the positive electrode roller is connected with the positive electrode of the measuring instrument; the negative electrode roller is connected with the negative electrode of the measuring instrument. The device disclosed by the utility model is used for solving the technical problems that the existing carbon fiber testing device and method are used for detecting only products off the production line, cannot realize long-distance complete inspection and are poor in timeliness; the device disclosed by the utility model can be used for judging the stability of the products by changes of resistance so as to realize on-line monitoring and guarantee nondestructive examination of the products and effective judgment on the stability of the products.
