2. Infrared thermometer - Wikipedia

   en.wikipedia.org/wiki/Infrared_thermometer

   The most common infrared thermometer is the spot infrared pyrometer or infrared pyrometer, which measures the temperature at a spot on a surface (actually a relatively small area determined by the D:S ratio). These usually project a visible red dot onto the center of the area being measured that identifies the spot being measured, but plays no ...

3. Meat thermometer - Wikipedia

   en.wikipedia.org/wiki/Meat_thermometer

   A meat thermometer or cooking thermometer is a thermometer used to measure the internal temperature of meat, especially roasts and steaks, and other cooked foods. The degree of "doneness" of meat or bread correlates closely with the internal temperature, so that a thermometer reading indicates when it is cooked as desired.

4. Thermometer - Wikipedia

   en.wikipedia.org/wiki/Thermometer

   An infrared thermometer is a kind of pyrometer . All objects above absolute zero emit blackbody radiation for which the spectra is directly proportional to the temperature. This property is the basis for a pyrometer or infrared thermometer and thermography. It has the advantage of remote temperature sensing; it does not require contact or even ...

5. Temperature measurement - Wikipedia

   en.wikipedia.org/wiki/Temperature_measurement

   Measurements of infrared radiation pertaining to sea surface temperature have been collected since 1967. Satellite datasets show that over the past four decades the troposphere has warmed and the stratosphere has cooled. Both of these trends are consistent with the influence of increasing atmospheric concentrations of greenhouse gases.

   Inset shows false color infrared thermograph of a roof on a sunny day; the white surfaces (colored blue in the thermograph) have been coated with an elastomer to reduce solar loading and have a surface temperature of approximately 60 °F (16 °C); the gray surfaces (colored red/white in the thermogram) are a standard asphalt (bitumen) coating and have a surface temperature of approximately 160 ...
