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.
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 objects 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.
Tamb: To display and adjust the real-time comparative scene temperature of target. The default setting of this
parameter is automatic adjusted by the internal temperature sensor. If needed, this setting can be adjusted
manually according to real temperature of some special scenes (like sky or snow) of measured target.
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.
