Abstract

An apparatus, system and method for temperature measurement of a target site, such a human body site. The invention includes an intelligent temperature probe configured to physically contact a target site and to communicate with a host device, which can be implemented as a hand-held device or as a personal computer. The host device can compute, store and display an accurate predicted temperature, or an actual temperature at thermal equilibrium, of the target site for each of a plurality of different intelligent temperature probes that each have unique and varied operating characteristics. A set of unique operating characteristics for each temperature probe is represented by information communicated between each respective temperature probe and the host device.
