A digital non-contact tympanic thermometer has a tympanic probe with an IR sensor at the end of the probe in which the digital non-contact tympanic thermometer can be converted to a digital non-contact non-tympanic thermometer for non-tympanic surfaces by placement of removeable probe cover over the tympanic cover in which the probe cover includes a parabolic condenser at the tip of the probe cover that increases gathering of incoming infrared energy.
