115
It refers to how close the measured result is to the reference. Ex: if the actual
temperature of an object surface is 100
℃
, and the accuracy is ±2
℃
, then the
measured temperature would be 98
℃
—102
℃
Verification
Verification is a process, which compares the measurement result and the object’s
standard value. Verification is not calibration; Verification records the deviation
while calibration corrects the result.
Color Palette
Color Palette determines how an image’s color is displayed. Based on different
measurement assignments, the thermal imaging display uses different color
contrast.
Color Isotherms
This function marks every point of the same temperature with the same color in
a certain range. It aids real-time analysis.
Cold spot and Hot spot
The point with the highest temperature in a certain region is called a ‘hot spot’.
Conversely, the point with the lowest temperature in a certain region is called a
‘cold spot’.
Emissivity (ε)
Emissivity is a measure of how much radiation is emitted from the object,
compared to that from a perfect blackbody of the same temperature. Emissivity
is a physical property of a measured object, which determines by its surface
characteristics, temperature, and wavelength.
RTC
RTC stands for Reflected Temperature Compensation. Some objects have high
reflectivity, which could induce false readings from reflecting thermal radiation
of higher temperature objects nearby. In short, when the observed object has
