HOLDPEAK 1850
Non-contact infrared thermometer
Instruction manual
- 30 ℃ TO 1850 ℃（- 22 TO 3362 F ）
1,Introduction:
1.Introduction
Compact, rugged and easy to use. Just aim and
push the button, read current surface temperat-
-ure in less than a second. Safely measure sur-
-face temperature of hot, hazardous or hard-to
-reach objects without contact.

2,How it work:
Infrared thermometer measures the surface temp-
-erature of an object. The unit's optics sense emi-
-tted, reflected, and transmitted energy which is
collect and focused onto a detector. The unit's
electronics translate the information into a temp-
-erature reading which is displayed on the unit.
For increased ease and accuracy the laser poin-
-ter makes aiming even more precise.
2.How it works
3,Caution:
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 30 minutes for unit to
stabilize before use).
--Do not leave the unit on or near objects of high
temperature.
--Static electricity.

4,Warning:
4.1 Do not point laser directly at eye or indirectly
off reflective surfaces.
4.2 The unit cannot measure through transparent
surfaces such as glass or plastic. It will measure
the surface temperature of these materials
instead.
4.3 Steam, dust, smoke, or other particles can prev-
-ent accurate measurement by obstructing by the
units optics.
4.4 When take measurement, point thermometer
toward the object to be measured and hold the
yellow trigger. The object under test should be
larger than the spot size calculated by the field
of view diagram.
4.5 Distance & spot size: As the distance from the
object increase, the spot size of measuring area
becomes larger.

4.6. Field of view: Make sure the target is larger
than the unit's spot size. The smaller target the
closer measure distance. When accuracy is
critical, make sure the target is at least twice as
large as the spot size.
4.7. Emissivity: Most organic materials and painted
or 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 for this, adjust the
units emissivity reading (see table below and
5.3 settings) or 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.
