The utility model discloses a broad spectrum automatically-identifying device used for supervising electric oil-consuming devices. The device comprises a micro passive ID chip electronic label, a handheld electronic label reader-writer, and a back-stage management system. The micro passive ID chip is arranged on an electric oil-consuming device, or test instruments or various articles which are related to process of electric oil-consuming supervision. Transport connection is established between the handheld electronic label and the back-stage management system. The device inputs supervisory parameter information to an electronic label inlaid on a tested object (data is written by an authorizer). When supervision and test are performed, a supervisor-used transceiver of the broad spectrum automatically-identifying device used for supervising electric oil-consuming devices is capable of fast and accurately receiving all parameter information within a range in a area with a certain radius, so that unsupervised and untested objects, or objects with expired testing time, unqualified testing objects, and objects normally supervised and tested can be discriminated, respectively. Further, a chromatographic instrument, a micro-water instrument, a scale, a glass syringe, other instruments used for supervising electric oil-consuming devices, and pharmaceutical reagent can be indentified and supervised in order to guarantee whether verification is performed or not and acquire the detected data.
