Introduction

Radiation is the transmission of energy in the form of waves or
particles through space. One type of radiation is electromagnetic
radiation which includes visible light, radio waves, microwaves,
and infrared (IR). You cannot see IR radiation but you can feel it
as heat. It behaves like visible light - it can be focused, reflected
or absorbed.
An IR thermometer uses a lens to gather IR radiation and focus it
on a detector. The detector converts the IR radiation into
electricity which can then be displayed as a temperature
measurement.
The Southwire 31212S Infrared (IR) Thermometer measures
surface temperature from -26° to 932°F (-32° to 500°C). The IR
thermometer has a 12:1 Distance-to-Spot ratio which means that
when you aim the thermometer at a surface that is 12-inches
away, the thermometer gathers temperature information from a
measurement area (“spot” size) of 1 inch in diameter. If the IR
thermometer is moved further from the object surface, the
measurement area or spot size increases.
Safety
• Use caution when the laser beams are on.
• Do not aim the laser beams at anyone’s eye or allow the laser
beams to strike the eye from a reflective surface.
• Do not use the thermometer near explosive gases, vapors or
dust.
• To avoid burns, understand that reflective objects can be
much hotter than the thermometer indicates.
• Replace the battery as soon as the low battery warning
appears on the LCD display.
• Do not use the thermometer if it appears damaged or is
operating improperly.
• Before using the thermometer, inspect the case.
Protection may be impaired. When in doubt, have the
thermometer serviced.
• This product should not be used for medical evaluations.
• If the thermometer is used in a manner not specified by the
manufacturer, the protection provided by the thermometer may
be impaired.
• Laser used for aiming purposes only.
When you press the trigger, two laser beams indicate the size of
the measurement area. Imagine a circle inside of the two lasers
and that is the approximate size of the area the thermometer is
collecting date from.
