as the spot size.
4. Emissivity: Most organic materials and painted or oxidized surfaces have an emissivity of 0.95.
Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate, cover
the surface to be measured with masking tape or flat black paint.
Range of normal body temperature at different ages:
A person’s body temperature varies by the time of day and
is
also affected by other external
conditions such as age, sex, skin color and many more. Please refer to the following table for
the normal temperature range of different age groups:
Age
Normal temperature (
℃
)
Normal degrees Fahrenheit (
℉
)
0~2 Years 36.4~38 97.5~100.4
3~10 Years 36.2~37.8 97.0~100,0
11-65 Years 35.9~37.6 96.6~99.7
>65 Years 35.8~37.5 96.4~99.5
Note: The body temperature of women and men is different. Generally 0.3 degrees higher
for woman than men.
