CD Compact Disk. Also called a CD ROM, for CD Read-Only Memory. The CD supplied with the
Thermal Imager contains software and manuals.
Celsius A temperature scale based on 0 °C as the freezing point of water and 100 °C as the boiling
point of water at a reference barometric pressure.
color palette, palette A thermal image color scheme. Generally, black is the coldest and white is the hottest, but you
can choose the colors that represent the intermediate temperatures in the scale. Palette is one
of the Setup menu choices in the Thermal Imager: IRON, RAINBOW and GRAY.
detector Also called “sensor,” the component that detects infrared radiation to determine temperatures.
The Thermal Imager’s detector is a microbolometer. (See “microbolometer” and “FPA.”)
detector, Infrared A transducer element that converts incoming radiant infrared energy striking its surface into an
electrical signal.
directional keypad The round group of arrow keys and center function key on the keypad.
display The screen on the Thermal Imager that presents thermal or visual images and operating menu
choices.
emissivity (ε) The ratio of infrared emitted by an object divided by infrared emitted from a blackbody at the
same temperature. The Thermal Imager allows you to select from a list of surface materials
to maximize accuracy of the temperature readings. This is called “adjustable emissivity.” (See
also “blackbody.”)
Fahrenheit A temperature scale based on 32 °C as the freezing point of water and 212 °C as the boiling
point of water at a reference barometric pressure.
field of view (FOV) Stated in angular degrees, the width and height of the area that the Thermal Imager senses all
incoming infrared energy to produce a thermal image.
