This document introduces the development of an alternative thermometer that achieves the same vertical dimensions as a mercury thermometer, along with heat resistance and vibration resistance. The dimensions (height) are equivalent to those of conventional mercury thermometers, featuring a mechanical structure with mounting screws that allow for direct replacement of mercury thermometers. The goal was to develop an electronic thermometer with a 10-year power supply life and a structure that is resistant to engine vibrations and heat.
