Infrared Laser Thermometer
Instruction manual
Introduction
Compact,rugged and easy to use. Just aim and push the
button, read current surface temperatures in less than a
second. It measures surface temperatures of hot,
hazardous or hard-to-reach objects without contact.
How it works
Infrared thermometer measures the surface temperature
of an object. The unit’s optics sense emitted,
reflected,and transmitted energy which is collect and
focused onto a detector. The unit’s electronics translate
the information into a temperature reading which is
displayed on the unit. For increased ease and accuracy
the laser pointer makes aiming even more precise.
Cautions
Infrared thermometer shoul
d be protected for the
following:
--EMF (electro-magnetic fields) from arc
welders,induction heaters.
--Thermal shock(cause by large or abrupt ambient
temperature changes allow 30 minutes for unit to
stabilize before use).
--Do not leave the unit on or near objects of high
temperature.
Warning
Do not point laser directly at eye or indirectly off
reflective surfaces.
1. When taking measurement, point thermometer
towards the object to be measured and hold on
to the trigger. The object under test should be
larger than the spot size calculated by the field of
view diagram.
2. Distance & spot size:As the distance from the
object increase, the spot size of measuring area
becomes larger.
3. Field of view: M
ake sure the target is larger than
the unit’s spot size. The smaller the target the
closer measure distance.When accuracy is
critical, make sure the target is at least twice as
large as the spot size.
4. Emissivity:Most organic materials and painted or
Model: LT-04
oxidized surfaces have an emissivity of 0.95
(pre-set in the unit ). 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.Measure the tape or painted surface when
the tape or painted reach the same temperature as
the material underneath

2. Locating a hot spot:To find a hot spot aim the
thermometer outside the area of interest, then
scan across with up and down motions until you
locate the hot spot.(please turn on the laser for
accurate measuring)

Maintenance
1) Lens cleaning:Blow off lose particles using clean
compressed air Gently brush the remaining

away with a moist cotton cloth.
2) Case cleaning:Clean the case with a damp
sponge/cloth and mild soap
Note:
1) Do not use solvent to clean lens.
2) Do not submerge the unit in water.
