How to get accurate temperature?
There are a lot of factors affecting temperature accuracy.
Here is a brief introduction to some typical parameters: emissivity, background temperature, distance, humidity and etc.
Note:
To get accurate temperature, you shall hold the camera stably and focus the camera well.
y
Emissivity:
All objects radiate infrared energy. The amount of energy radiated is based on two primary factors: the
surface temperature of the object and the emissivity of object’s surface.
The default emissivity is 0.98, which is applicable to most surfaces.
For some special materials or surfaces, please refer to the emissivity table to find a right emissivity value.
You can change emissivity between 0.01 and 1.00 in menu Para and Emissivity.
y
Tamb:
To display and adjust the real-time comparative scene temperature of target. The default setting of this

Press
button and
button to bring the submenu of parameter setting, then choose “Tamb” and select
“Set” option to set the value manually by press
button and
button. The new measurement will be
based on the saved tamb value until re-enter the “Tamb” option and exit, which will activate the default automatic
mode.

y
Relative Humidity:
To set relative humidity percentage value between 0 and 100 according to the practical
environment.
