Non-contact infrared thermometer
Instruction manual
Introduction
Compact, rugged and easy to use. Just aim
and push the button, read current surface
temperature in less than a second. Safely
measure surface temperature of hot,
hazardous or hard-to-reach objects without
contact.
Cautions
Infrared thermometer should be protected
from the following:
--EMF (electro-magnetic fields) from
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.
Do not point laser directly at eye or
in-directly off reflective surface.
1. When taking measurement, points
thermometer toward the object to be
measured and hold the yellow trigger. the
object under measuring 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: Make sure the target is larger
than the unit's spot size. The smaller the
target, the closer the measure distance.
When accuracy is critical, make sure the
target is at least twice as large as the spot
size.

Warning
How it works
Infrared thermometer measure the surface
temperature of an object. The units optical
,
system sense the object s emitted energy
with different wavelength. It is collected and
,
focus onto a detector. The unit s electronics
system translated the information into a
temperature reading which is displayed on
the unit.
