Infrared Thermometer

An infrared thermometer is a thermometer which infers temperature from a portion of the thermal radiation sometimes called blackbody radiation emitted by the object being measured. They are sometimes called laser thermometers if a laser is used to help aim the thermometer, or non-contact thermometers to describe the device’s ability to measure temperature from a distance. By knowing the amount of infrared energy emitted by the object and its emissivity, the object’s temperature can often be determined. Infrared thermometers are a subset of devices known as “thermal radiation thermometers”.

Sometimes, especially near ambient temperatures, false readings will be obtained indicating incorrect temperature. This is most often due to other thermal radiation reflected from the object being measured, but having its source elsewhere, like a hotter wall or other object nearby even the person holding the thermometer can be an error source in some cases. It can also be due to an incorrect emissivity on the emissivity control or a combination of the two possibilities.

The most basic design consists of a lens to focus the infrared thermal radiation on to a detector, which converts the radiant power to an electrical signal that can be displayed in units of temperature after being compensated for ambient temperature. This configuration facilitates temperature measurement from a distance without contact with the object to be measured. As such, the infrared thermometer is useful for measuring temperature under circumstances where thermocouples or other probe type sensors cannot be used or do not produce accurate data for a variety of reasons.

Some typical circumstances are where the object to be measured is moving; where the object is surrounded by an electromagnetic field, as in induction heating; where the object is contained in a vacuum or other controlled atmosphere; or in applications where a fast response is required, an accurate surface temperature is desired or the object temperature is above the recommended use point of a contact sensors, or contact with a sensor would mar the object or the sensor, or introduce a significant temperature gradient on the object’s surface.

Our Opinion:

Essentially the paranormal majority rules cold spots are a form of spirit manifestation. Since cold spots are short-lived and tend to move about, conventional thermometers are not fast enough to record the phenomenon. The instant-reading infrared digital thermometers are the most accurate for documentation purposes, providing comparable data throughout an investigation. For ambient or background temperature readings, a common thermometer or thermocouple device is sufficient. When used appropriately digital thermometers can be very useful during an investigation. Some groups use this piece of equipment and some do not. For this reason we say this is a:
