PORTABLE ELECTRONIC THERMOMETER AND METHODS OF TEMPERATURE MEASUREMENT

摘要

An electronic thermometer having a probe for introduction into a region having a temperature to be measured. The probe includes a temperature sensitive impedance element having a heat sensing relationship with the region when the probe is introduced thereinto. Timing means is provided for initiating a predetermined timing interval upon the temperature of the element exceeding a preselected level following introduction of the probe into the region. Circuitry measures the temperature of the element at the completion of the timing interval. A meter provides means for indicating a temperature which is a function of the measured temperature of the element at the completion of the timing interval, the indicated temperature being a substantially accurately extrapolated representation of the actual temperature in the region.
