Abstract

An electronic thermometer having ergonomic and efficiency features. The thermometer includes a display and a control panel, defined by at least one button, disposed above the display. The thermometer is easy and comfortable to hold and allows the user to operate the thermometer with one hand. The thermometer holds a probe and a container of probe covers in a convenient and compact configuration. A battery door is particularly constructed to avoid accidental opening. A bottom of the thermometer is formed to hold the housing in an upright position when the bottom is placed one a horizontal surface.
