micro IR-200 Non-Contact Infrared Thermometer
Set-Up and Operation
Do not look into the laser beam. Looking into the laser beam may be
hazardous to the eyes. Do not look at the laser beam with optical aids
(such as binoculars or telescopes).
Do not direct the laser beam towards other people. Make sure the laser
is aimed above or below eye level. Laser beams may be hazardous to
the eyes.
Take appropriate precautions when working near electrical, moving or
hot parts. Close contact may cause electrical shock, entanglement,
burns and other serious injury. Protective equipment may be required.
Set up and operate the infrared thermometer according to these
procedures to reduce the risk of injury or incorrect measurements.
Set-Up
1. Check for an appropriate work area as indicated in the
General Safety Section .
2. Inspect the object being measured to and confirm that you
havecorrect equipment for the application. See the
Specifications section for range, accuracy and other
information.
There are a variety of factors that can affect the accuracy of
the micro IR-200, including:
Field of view
– The micro IR-200 uses two lasers to project
points on either side of the area to be measured. These
points indicate the approximate diameter of the area (the
“Spot”) that the temperature is being measured in. As the
micro IR-200 moves further (D) away from the surface, that
area and spot size (S) increases. The area is approximately
1
/
30
times the distance to the surface. (See Figure 7 . )
Figure 7
– Field Of View
The spot should always be smaller than the surface. The
smaller the surface, the closer the micro IR-200 should be to
the surface. For the best accuracy, the surface should be
twice as large as the spot.
Emissivity
– Emissivity is a term use to describe energy
emitting characteristics of materials and has a value ranging
from 0 to 1. The micro IR-200 allows adjustment of the
emissivity value from 0.10 to 1.00 to calculate temperatures.
If the emissive property of a surface is unknown, an
emissivity of 0.95 can be appropriate for many applications,
such as painted surfaces. Values of emissivity for common
materials are included in
Figure 8.
