How ghost hunters use Infrared Thermometers
How do infrared (IR) thermometers work?
IR thermometers capture the invisible infrared energy naturally emitted
from all objects. Infrared radiation is part of the electromagnetic
spectrum which includes radio waves, microwaves, visible light,
ultraviolet, gamma, and X-rays. Any object warmer than absolute zero emits energy somewhere within that range.
How does this apply to ghost hunting?
IR thermoemters read the surface temperatures of things. The wall below is
giving off a infrared heat signature of 78 degrees and the IR
thermometer picks it up. If something invisible to the naked eye gets
in between the wall surface and the thermometer and it has a lower you
IR heat signature you will get a colder temperature reading. This is
“impossible” but we do record these anomalous temperature drops in
haunted locations and that’s why they are so significant, they can’t be
explained.
Yes. Measuring moving targets is one of the benefits of using non-contact infrared thermometers.
Do IR thermometer send out any beams?
No,
the IR thermometer just receives in infrared hear signitures coming off
any surface you point it at. Some models do have a laser
but this is not needed in ghost hunting. The laser pointer help
mechanics using a IR thermometer to pinpoint an exact part they need to
check the temperature of.
How close do I have to be to an object to take its temperature?
Distance does not affect the measurement. However, infrared sensors
measure the energy from a circular spot on the target, and the size of
that spot is a function of the distance between the sensor and target.
The farther away from the target the sensor is, the larger the spot.
Consequently, distance is only limited by the size of the object you
want to measure. Most IR thermometers have a maximum measuring
distance of approximately 100 feet (30 meters), depending on
atmospheric conditions. High humidity can reduce the
effectiveness and accuracy of IR Thermometers.
How ghost hunters use Ambient Air Thermometers
 
These wokr the way
that most of us understand a thermometer to work. It
reads the temperature of the air that is right around the thermometer
and/or around it's sensing bulb. Most
remember the highest and lowest temperatures it has read so you can see
if there have been any big changes in an area.
