Emissivity  refers  to  a  material’s  ability  to  emit  infrared  energy,

compared to an ideal black surface at the same temperature.  The

ratio varies from 0 to 1, and each material has a specific emissivity

associated  with  it.  The 

PosiTector 

IRT

has  built  in  emissivity

settings  for  certain  materials  as  well  as  a  user-adjustable

emissivity option (pg. 6).
Most organic and painted surfaces have an emissivity of around

0.95,  and  are  ideal  surfaces  for  accurate  infrared  temperature

readings. Shiny or reflective surfaces can be difficult to measure

with  an  infrared  thermometer,  as  they  tend  to  reflect  ambient

infrared energy instead of their own. To compensate for this, cover

such surfaces with flat paint or a piece of electrical tape. Allow the

paint or tape to acclimate to the surface’s temperature, and take a

measurement over the paint or tape.

Distance to Spot Ratio (D:S)

The distance to spot ratio refers

to  the  relationship  between  the

diameter  of  the  area  being

measured  compared  to  the

instrument’s  distance  from  the

area.  As  the  distance  (D)  from

the  target  increases,  the  spot

size  (S)  of  the  area  being

measured  by  the  unit  becomes

larger.  The  D:S  ratio  of  the

PosiTector 

IRT

is  5.7:1.  For

example, when the instrument is

100  cm  (40  inches)  from  the

target, the spot size will be about

18 cm (7 inches) in diameter.
