Types of Infrared Thermometers
There are three different types of infrared thermometers, which are spot infrared thermometers, infrared cameras, and infrared line scanning systems. These sections will describe each type in depth, but if you aren’t satisfied, you can look for more detailed information online on other pages.
Spot Infrared Thermometers
Also called an infrared pyrometer, these types of infrared temperature guns measure the temperature at one spot on a surface, which is a relatively small area. Typically, they will point a red dot on the area being measured, and aren’t used as much professionally as the other two types of IR thermometers.
Most spot thermometers are used as household tools to measure anything from ovens and fridges to air conditioners. A great example is the Fluke 561 Non-Contact Infrared Thermometer with laser targeting. It has a four and a half star review out of five stars. With over fourty reviews, that’s a pretty solid showing by this spot thermometer. It has the ability to measure from -40? to 1022? Fahrenheit and has a spot ratio or twelve-to-one.
Specifically, it measures hazardous or inaccessible objects, moving targets, and targets with high temperatures. The Fluke weighs 2.25 pounds, and it is powered by AA batteries.
Infrared thermal imaging cameras measure the temperature of several points over a large area to create a two-dimensional thermogram, where each pixel represents a temperature.
Compared to spot or scanning thermometers, infrared cameras are used more for bigger areas and is more processor- and software-intensive. Another difference is that they are much more expensive than spot thermometers.
IR cameras are used for perimeter monitoring by the military or security guards, inspecting and quality measuring of manufacturing processes, and monitoring enclosed spaces with extreme temperatures for safety and efficiency. The FLIR E4: Compact Thermal Imaging Camera with 80 x 60 IR Resolution and MSX is one of the best thermal imaging cameras on Amazon. It is an expensive little tool, but with a four and a half star out of a five star review, the quality that comes with the price makes it worth every dollar.
It has a 3” 320 x 240 color LCD display that shows the thermal areas that are targeted, it has a 640 x 480 digital camera for storing images, and it has a range of -20? to 250? C, or -4? to 482? F. It also has a four hour battery life sourcing from a swappable Li-ion battery. Overall, this is one of the top rated infrared cameras on Amazon.
Infrared Line Scanning Systems
Infrared scanning systems scan bigger areas than spot thermometers, but not quite as large as that of infrared cameras. These types of infrared thermometers are basically spot thermometers pointed at a rotating mirror.
Manufacturing companies involved with conveyors, such as producing glass or metal sheets by sending them through an oven, especially use infrared line scanning systems. Generally, they are the largest physically of the three different types of infrared systems, and they are typically used for keeping tabs on factory conveyor lines and very hot or very cold sectors of the factory.

How Do Infrared Thermometers work?
Infrared thermometers measure temperature without making contact with the object being measured.? They achieve this by taking advantage of a phenomenon called black body radiation.? Black body radiation is a measure of the vibration of the molecules in an object or substance.
Heat is a function of the movement of molecules, so the temperature of an object is a function of how fast its component molecules are moving.? As the molecules move, they emit infrared radiation, which functions much the same as visible light except that our eyes are not equipped to detect it.
To measure this type of radiation, we need an infrared thermometer. An infrared laser thermometer usually consists of three basic parts: a lens, a thermopile, and a detector.? When pointed at a source of infrared radiation, the lens focuses the infrared radiation being emitted onto the thermopile, which then converts the infrared radiation into heat.? The more infrared light is focused onto the thermopile, the more the thermopile heats up.? From here, the infrared thermometer works much like a household digital thermometer.? As the thermopile heats up, it converts this heat into electricity.? The electricity in turn is sent to a detector, which translates the electrical input it receives into a temperature for the object being measured and send this figure to a display which the user can read.
How to use an Infrared Thermometer
Most consumer application gun style infrared thermometers, like those used for home projects and cooking, will have the same basic functionality.? Turn the thermometer on, point it at the surface you want to measure, hold the trigger or read button, and it will instantly give you a temperature.? However, every infrared thermometer is going to be a little different in its operation.
As such, the best way to learn how to use a particular unit is a careful reading of the owner’s manual.? One thing to keep in mind that will be unique to each model of thermometer equipped with a laser guide is how the laser point relates to the area actually being measured by the optics.
With some guns, the laser indicates the center of the area measured, in others it is the top or the bottom.? Some models will have two lasers to delineate the top and bottom of the range. But with all laser aided models, the size of the area measured will vary based on the distance to the surface.
Another?thing to keep in mind when reading infrared cooking thermometer reviews and deciding on which model best suits your needs is the optimal optic distance.? Knowing the optimal distance for your particular thermometer will allow you to get the most accurate temperature readings.? Also keep in mind that while they are a quick and convenient way to measure the temperature of food while it is cooking, even the best infrared thermometer for cooking can only measure the temperature on the surface of an object.
Depending on the thickness of what you are cooking, the surface temperature may or may not give you any insight as to the food’s internal temperature. However, for cooking temperature sensitive things like meat, the only way to be certain it is done and safe to eat is with a probe style meat thermometer.
Infrared Thermometer Applications
Because infrared thermometers are able to measure an object’s temperature from a distance, they are ideal for situations where the object being measured is sensitive, inaccessible, or dangerous to get close to.? Infrared thermometers are used by energy consumption experts to determine what parts of a structure – from a house to large corporate buildings – are the biggest loss points for heating or cooling energy.
Firefighters use them in determining what parts of a fire are burning hottest and therefore what points on a structure are most at risk of collapse and where they can safely enter.? Infrared thermometers are often used in industrial applications as well, monitoring the temperature of things which cannot safely be contacted, like molten steel, glass, and certain steps in the petroleum refining process.
Ear thermometers – like the ones usually used at doctors’ offices – are just one example of medical infrared thermometer.? A person’s ear drum maintain a temperature very close to that of the person’s core, and so is a reliable and easy way to measure temperature.? However, the ear drum is a very fragile and sensitive organ, and touching it to measure temperature would likely damage it.? Thus, an infrared thermometer – which although it gets very close does not need to touch the ear drum – is the perfect way to measure temperature in this setting.? The most common household application, though, is cooking thermometers.
