Non-contact infrared thermometer
Instruction manual
1、Introduction
Compact, rugged and easy to use. Just aim and push the
button, read current surface temperatures in less than a
second. Safely measure 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 transmitted energy which
is display on the unit. For increased ease and accuracy the
laser pointer makes aiming even more precise.
Cautions
Infrared thermometer should 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 1 hours for unit to stabilize
before use).
--Do not leave the unit on or near objects of high
temperature.
Warning
Do not point laser at eye or indirectly off reflective
surfaces.
1. When take measurement, point thermometer toward
the object to be measured and hold the yellow trigger.
The object under test should be large 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 large.
3. Field of view: Make sure the target is larger than the
unit’s spot size. The smaller the target the close
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
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. Measure the tape or painted surface when
the tape or painted reach the same temperature as the
material underneath.
