What is an Infrared Thermometer?

Infrared Thermometers have become quite essential, and from the industry use, the attention has shifted on the personal use. Usually people use thermometers in order to measure heat, but now they may purchase IR thermometers (also known as pyrometers), being able to measure much higher temperatures.

A pyrometer is a device used to measure very high temperatures, like the ones from a kilt or a furnace. In such cases usual thermometers aren’t efficient. The difference between a pyrometer and a thermometer is that temperatures measured by a pyrometer are much higher and efficient than the ones measured by a usual thermometer.  A pyrometer uses the heat that radiates from an object and it measures the temperature without touching it, so it can be used in many different situations.

Usually it’s used by smelter industries, in the fabrication of steam boilers and hot air balloons, and it may be very useful for turbo-charged diesel engines. These applications are very complex and need a precise measurement tool and infrared thermometers offer a great precision. However, even air conditioner repairmen use them when necessary. Usually they use the IR thermometers. They also may be used in order to identify a situation that needs further analysis, such as the measurement of the hot air coming out during a ramp check. The area of use is growing, and more industries are going to need such pyrometers. Now they are available in a certain number of models.

Infrared pyrometers allow the measurement of temperature in such applications where one cannot use conventional sensors. There are many places where one could use an infrared thermometer, such as moving machinery for instance.

Infrared Thermometer Uses

Infrared thermometers (or sometimes called laser thermometers, non-contact thermometers, or temperature guns) are incredible tools used for measuring all sorts of temperatures, in situations that most cannot even imagine! In order to get a better idea of who takes advantage of this incredible tool, we will walk through a couple of their more popular uses.

In the kitchen: Those preparing food, from professional chefs to detailed stay-at-home Moms, can use infrared thermometers to measure temperatures in the kitchen or outside when weekend grilling. Whether looking for exact temperatures of your boiling oil or a frying pan, the laser thermometer will inform you quickly and easily.

Around the house: Whether contract workers or inspectors, non-contact thermometers are great for checking surface temperatures around the house. Plumbers can check pipes for leaks of hot liquids. Mothers can even use these great tools to check the temperature of their baby! Beyond the pipeline and the wall temperatures, infrared thermometers are making their way into the medical field.

In the garage: You may use it to check the breaks of your car. In this way you may be able to prevent it from breaking down. Usually when you deal with mechanic equipment, the first sign of trouble lies in an increased temperature. If this is the case, you need to check the equipment in order to detect eventual problems and prevent system failures. This is when you may use pyrometers such as the Fluke IR thermometers. They were manufactured in such a way that they can be used by anyone, and not only professionals. Making regular inspections, you may prevent catastrophic failures.

Construction: As gas lines continue to be routed and constructed, the lines must be assessed for safety and leaks. Gas is a silent escapee visually but with an infrared thermometer, a technician can pick up leaks right at their source. These uses are great, but there are even bigger jobs taking advantage of these great tools.

Firefighters: By far, the most important use is for the firefighters. This little device keeps our heroes safe. During the simulations they place an infrared thermometer in a building and they are able to see the actual temperature. Now they will be more prepared for actual interventions. It is a great way to feel what they will be facing in reality. In this way they will be able to see and feel what they will be facing on the field, correcting their behaviors and reactions.

Outside of the box: Those who study space, particularly the sun, are constantly observing the sun – as well as other stars – with infrared thermometers. Hot spots on other planets and stars are easily picked up and measured thanks to the details that can be gathered by non-contact thermometers.

From the homeowner to the auto mechanic, infrared temperature guns have many uses.  And at prices ranging from less than $20 to the more advanced thermometers at $100, these tools are inexpensive just to keep on hand because you just never know when you may need it.

How to pick the best infrared thermometers?

Many factors need to be considered and here are primary specifications:

  • Temperature Range – Different infrared thermometers always have very different temperature range. Some are designed for relatively limited ranges while others are designed for temperatures which rise and fall violently.
  • Optical Resolution – It is also considered to be field of view and is usually referred as a ratio. It is necessary to state that the distance between the IR thermometer and the surface being measured can be greater if the ratio is greater .So as to obtain a precise reading, the whole surface which is being measured must descend to the field of view of the IR thermometer. Some products equip with a laser sight which shows the center of the area being measured ,others shows a round pattern of dots which represents the whole area being measured.
  • Emissivity – This measures the ability of a material to reflect absorbed energy . The more radiative a material is, the farther the emissivity is to 1. The blacker and duller a material is, the higher its emissivity. IR thermometers can either have a adjustable or fixed emissivity.
