What does “distance to spot ratio” mean?
The laser spot needs to be showing inside the
target area. An 8:1 “distance to spot ratio” means
you are measuring a 1” diameter area at a
distance of 8”.
How far can I measure?
Distance is unlimited. The size of the target area sets
the limit on distance for accurate measurements.
Example: If the area you wish to measure is 1 foot in
diameter, then you will need to be within 8 feet to
record an accurate temperature.
What is the smallest target I can read?
Approximately one-half inch in diameter.
How do I turn the laser on and off?
While holding the Power On button down you can
toggle the Lock On button for either laser on or laser
off operation. When the laser is activated the laser
displays this icon
What is emissivity?
This is a ratio of an object’s infrared emission
compared to a theoretical black body, considered 1.
Emissivity is always less than 1. Adjustable
emissivity allows your non-contact thermometer to
be adjusted to the surface you are checking to
makereadings more accurate.
How do I adjust the emissivity of my
contact/noncontact 375, 376, 377?
The 375, 376, and 377 feature adjustable emissivity
and contact probe capability. This is very useful for
determining the emissivity of any surface condition.
Simply use the contact probe and record surface
temperature. Next use the IR gun and adjust the
emissivity until the temperature matches the reading
of the contact probes. Copper pipe produces
different emissivity properties, ranging from 0.02 to
0.78, due to oxygen oxidation and curvature. You
will now have the most accurate reading in the IR
mode for that surface.
How can I make measurements more accurate if I
don’t have my contact probe or have a fixed
emissivity thermometer?
Painting the surface being measured matte black will
make temperature readings more accurate. A piece
of black tape can also be used.
