An apparatus for recording temperature and engine speed of a refrigerating/freezing vehicle is provided to allow a user to easily check the temperature and engine speed by displaying and printing out the temperature and engine speed in a graph or a table through an incorporated printer. An apparatus for recording temperature and engine speed of a refrigerating/freezing vehicle comprises a temperature sensor module(12), a tacho sensor(14) measuring engine speed of the vehicle, a memory(18) storing the measured temperature and engine speed, a display unit(22), a built-in thermal printer(24), an input unit(20) and a processor(10). The temperature sensor module converts the temperature of the vehicle into digital data for serial communication. The display unit indicates the temperature and engine speed, and the built-in thermal printer prints out temperature and engine speed.
