The utility model provides a temperature of test of electric field fingerprint technique is reduced device of error, belongs to pipeline nondestructive testing technique field. There is the pipeline that awaits measuring (1) that the medium flows through and sets up the reference board on the pipeline that awaits measuring (1) surface, its characterized in that including inside: be provided with operation compensation arrangement (2) on the surface of the pipeline that awaits measuring (1), refer to the board and fix on operation compensation arrangement (2) surface, being connected with on operation compensation arrangement's (2) shell and making its inside media?rotation unit that forms the inner loop, at the inside temperature compensating unit that is provided with of operation compensation arrangement (2), control is realized by the controller to media?rotation unit and temperature compensating unit. Through the utility model discloses a temperature of test of electric field fingerprint technique is reduced device of error embodies the influence of temperature to the pipeline that awaits measuring through referring to the board totally, has realized judging the accurate of the pipeline circumstances of corroding of awaiting measuring through the electric field fingerprint technique.
