Temperature Measurement

All objects radiate infrared energy. The quantity of energy radiated is based on
the actual surface temperature and the surface emissivity of the object. The
Imager senses the infrared energy from the surface of the object and uses this
data to calculate an estimated temperature value. Many common objects and
materials such as painted metal, wood, water, skin, and cloth are very good at
radiating energy and it is easy to get relatively accurate measurements. For
surfaces that are good at radiating energy (high emissivity), the emissivity
factor is 90 % (or 0.90). This simplification does not work on shiny surfaces
or unpainted metals as they have an emissivity of 0.60. These materials are
not good at radiating energy and are classified as low emissivity. To more
accurately measure materials with a low emissivity, an emissivity correction is
necessary. Adjustment to the emissivity setting will usually allow the Imager
to calculate a more accurate estimate of the actual temperature.
To prevent personal injury, see emissivity information for
actual temperatures. Reflective objects result in lower than
actual temperature measurements. These objects pose a
burn hazard.
Surfaces with an emissivity 0.60 make reliable and consistent
determination of actual temperatures problematic. The lower the
emissivity, the more potential error is associated with the Imager's
temperature measurement calculations, even when emissivity and
reflected background adjustments are attempted and performed
properly.
More information is available on emissivity. We recommend the study of this
topic to get the most accurate temperature measurements.
SmartView
SmartView software is supplied with the Imager. This software is intended
for Fluke Imagers and contains features to analyze images, organize data and
information, and make professional reports. SmartView allows audio
annotations and IR-PhotoNotes to be reviewed on a PC. SmartView is used to
export IR and visible images as .jpeg, .jpg, .jpe, .jfif, .bmp, .gif, .dip, .png, .tif,
or .tiff formatted files.
