A probe tip in combination with a seal assembly that prevents debris and other contaminants from entering the probe tip. In the preferred embodiment, the seal comprises a tube with a filter holder assembly attached at the distal end of the holder. The filter holder assembly includes an infrared filter seated inside a screw-on member that is attached to a holder member with a sealing member located directly behind the infrared filter. During manufacturing, a predetermined force is applied to the proximal end of the tube which drives the distal end of the tube and filter holder assembly against the probe tip opening, thereby forming a watertight seal thereto. In alternative embodiments, the seal assembly may be comprised of a collar and gasket combination instead of a filter holder assembly.

The present invention is directed to an electronic device for sensing and indicating the presence of electromagnetic interference in the vicinity of a electronic thermometer and preventing the display of a core body temperature reading when the electromagnetic interference exceeds a predetermined threshold. Disclosed is a tympanic thermometer comprising circuitry and a microprocessor that takes a a plurality of voltage readings from the null input of an operational amplifier in the circuitry. After taking into account ambient temperature conditions into the temperature calculations, the microprocessor compares the average value of the voltage readings taken from the null input against a predetermined threshold in the memory of the microprocessor. If the value exceeds the predetermined threshold, then the microprocessor prevents the display of the core body temperature and directs a display to write an error message. However, if the value does not exceed the predetermined threshold, the microprocessor directs the displays the core body temperature taken by the tympanic thermometer.
