Abstract
A probe assembly of an infrared thermometer is capable of detecting the surface temperature of a thermal radiation source and is suitable for holding over human skin or inserting into a patient's ear canal for accurately taking human body temperature. The probe assembly comprises a taper plastic tube, a conductive shell, an infrared radiation sensor and an adiabatic supporter, wherein the plastic tube has a radiation collection end and the conductive shell has a first open end. The infrared radiation sensor is placed in the first open end of the conductive shell, and has a base against the adiabatic supporter. The infrared radiation sensor has a hot junction toward the first open end of the conductive shell and a cold junction toward the adiabatic supporter.
