A method and apparatus for recording utility meter readings is disclosed. The apparatus includes a solid state memory an internal clock and an input/output unit which, among other things, causes meter location and identification information to be written into memory, and data representing the respective meter readings and the time of each reading to be read out of the memory unit into a central processing unit. A keyboard is utilized to introduce meter readings into the memory and to control the addressing of the memory as each of a plurality of meters is located, identified and the data displayed thereon entered into memory. A visual display unit displays the location of the meter to be read, the meter identification and the meter reading entered via the keyboard. A comparator circuit within the recorder compares the meter reading with expected predetermined maximum and minimum limits for the meter reading and generates an indicator signal to the display when the meter reading does not fall within the predetermined bounds. The meter is portable, is powered by batteries and is programmable to provide the location and identification of a plurality of meters as desired.
