Emissivity : in order to obtain more accurate measurement results, you need to set the emissivity
according to the target to be measured before each measurement, instead of using the default
configuration. Emissivity refers to the ratio of the radiant ability of an object to the radiant ability of a
blackbody at the same temperature, which is relative to the reflectivity of the object. The lower the
emissivity, the higher the proportion of energy being reflected. The higher the emissivity, the lower the
proportion of energy being reflected. For example, the emissivity of human skin is 0.98, and the
emissivity of printed circuit boards is 0.91. For more information on emissivity, you can click the
Emissivity button or refer to the quick start guide in the package or inquire from other sources.

Tianxuan Mx20 Series Handheld Thermal Camera·User Manual

Ambient temperature : the reflection temperature of the object surface will affect the
measurement result, especially when the object emissivity is low or the object temperature and the
reflection temperature differ greatly, this effect will increase. So the result needs to be compensated
to eliminate influences of the surface reflection temperature. However, it is usually difficult to
determine the reflected temperature of an object. The ambient temperature can be used to replace
the reflected temperature in actual measurement.

Tianxuan Mx20 Series Handheld Thermal Camera·User Manual

Distance : distances have effects on the measurement results. In order to get accurate
measurement, distance information of the object is necessary for the thermal camera to compensate
the result.
