The invention discloses a measurer with a storage function. The measurer comprises a shell, a measurement unit and a battery chamber, wherein the measurement unit comprises an electric parameter acquisition module, a local storage module, an embedded type programmable micro processor and a display unit; the electric parameter acquisition module is used for acquiring electric parameter signal data and inputting the data to the embedded type programmable micro processor for data validness identification processing; the embedded type programmable micro processor is connected with the local storage module and is used for storing the electric parameter signal data which are identified to be valid; the display unit is connected with the embedded type programmable micro processor and is used for receiving the electric parameter signal data and displaying state information of the electric parameter signal data subjected to identification processing. According to the measurer with the storage function, a data validness identification module in the embedded type programmable micro processor is used for performing validness identification on the acquired data, so that an identification process of an operator is avoided, and the labor intensity is alleviated; meanwhile, the data acquisition efficiency is improved, and an active effect is achieved for the future data processing process.
