Factors That You Need to Consider Whenever You Buy an Infrared Thermometer
There are several things to consider when purchasing an infrared thermometer and we will cover them in this next section.
Having precise measurements is essential, especially when working in a commercialized kitchen, when working with expensive machines, or in dangerous situations wherein accuracy can literally mean life or death.
For example, whenever you use a digital prototype in applications for food safety, it is vital to get accurate and specific readings every time.
Review the specs of your model.
You will get great results whenever it is more precise for the work you need to do.
Range of Temperature
Consider the temperature range that you would need for your application.
For example, if you only need a IR thermometer at home to measure the surface temperature of your air conditioner or grill, you wouldn’t need an extended temperature range.
However, if you are planning to have your laser infrared thermometer used whenever you work in an industrial setting with motorized engines and machinery, it would be best to get one with a higher temperature range.
Ratio of Distance To Spot
In D:S or ratio of distance to spot is the distance between the IR thermometer and the surface you want to read.
For example, a model that has a D:S ratio of 12:1 will approximately measure a diameter area of one inch whenever it is a foot away.
Once you get farther away from your target, the measurable area of the surface will become more extensive.
This can have an impact on the accuracy of your readings if you want to only get the measurement of a small area.
As an example, if you want to have an area of 2-inches measured from a meter away using a model with a D:S ratio of 12:1, the results that you’ll get will not be accurate.
This is because the thermometer would also have the temperature that is not within the area that is predetermined measured whenever you want to.
So, in essence, the ratio D:S will allow you to have an idea of the best distance to get a precise reading.
Consider how often as well as the purpose of using a laser infrared thermometer.
The laser thermometer that is best for you may not be the one that is most expensive.
Ensure to consider the features that can provide you the best value before opting to decide on buying anything.
Involved in Emissivity is the surface’s capacity to have thermal radiation emitted.
The 0.95 fixed emissivity settings are what infrared thermometers have.
These can take the readings of any high emissivity surface.
Because of that, the surface can be efficient in radiating the object’s temperature.
It can be fine whenever you take the readings of surfaces in dark matte-like tiles, walls, or asphalt.
However, because of the fixed settings in emissivity, it can lead to problems.
It happens whenever you measure reflective surfaces that have low ratings in emissivity.
For example, polished metal can provide false readings whenever the emissivity settings don’t get adjusted.
Adjustable settings in emissivity from 0.10 to 1.00 that a thermometer gun can feature can be more accurate whenever the thermometers get calibrated to the surface that you want to measure.
What Are The Uses of Infrared Thermometers?
You can use infrared thermometers to measure various objects’ surface temperatures in different applications and industries such as:
- HVAC—Professionals in the cooling and heating industry use infrared thermometers to check equipment and diagnose heat-related problems with HVAC systems like malfunctioning coils, insulation problems, and duct leaks.

- Home Use—Having the IR temperature gun in your home has many uses, like checking for cooling, heating, and insulation problems. It can also check issues in crafting beer, making soap, working on cars, cooking on any grill, and a lot of other jobs in home improvement or hobbies that people love to do.
- Medical—Infrared thermometers are medically essential in measuring an animal or humans body temperature.
How to Use an Infrared Thermometer
Have the device turned on, and then choose if you want to measure your temperature in Celsius or Fahrenheit.
Carefully review the instruction manual so that you are familiar with your device’s D:S ratio.
With this, you can be highly accurate when you take measurements.
In general, the closer you get to the surface, the more precise the measurement will be.
However, always remember that getting too close to any extremely hot object may be unsafe – use your best judgement.
Whenever you have a model with adjustable emissivity, have the emissivity changed to its optimal setting.
Allow the laser to guide you and have the thermometer pointed at what you desire to measure and then pull the trigger so you can view the displayed temperature.
Make sure to choose a spot that isn’t too near to any object with temperatures that can be vastly different.
Avoid using your device whenever you want to measure anything that has shiny or highly reflected surfaces without having the emissivity adjusted.
Frequently Asked Questions on Infrared Thermometers
Question: What Is the Infrared Thermometer?
Answer: Infrared thermometers are instruments used to measure the temperature of a surface without coming into physical contact with said surface.
They work by inferring the temperatures that have basis on thermal radiation emitted by a specific object.
Once you know the emissivity of an object and how much infrared energy it is emitting, you can gauge the apparent temperature of the object.
Since the infrared thermometer is non-contact, it employs a laser that can help the users in aiming the thermometer.
That is why people sometimes refer to them as laser thermometers.
Infrared thermometers are used in industrial settings where accurate and fast temperature readings from a certain distance are required whenever the surface is not within reach.
For example, the probe can’t get inserted into the item to be measured, or the temperature of the object is way too extreme to be measured at a close distance.
Question: How Does the Infrared Thermometer Work?
Answer: The infrared thermometer can work through a lens that focuses on the light that comes from any object.
This light is in the form that people call infrared rays. It funnels into a detector that they refer to as a thermopile.
Inside the unit, the thermopile works to absorb IR radiation and then allows it transform into heat that eventually converts into electricity.
It then works on measuring how much electricity is generated and then displays it on the thermometer’s screen.
Question: What Are The Temperatures That Infrared Thermometers Measure?
Answer: IR thermometers are capable of measuring temperatures in a range from too high to below freezing point.
The available range when it comes to temperature measurements would depend on every specific product.
As an example, we recommend the Fluke 62 MAX Plus.
It can measure a range of -30° Celsius to 650° Celsius or -22° Fahrehheit to 1202° Fahrenheit.
It comes with an accuracy of the reading at ± 1.0% or ± 1°C from 0°C to 650°C.
The laser infrared thermometers that are more expensive come with a greater distance and a more extensive measurement range that can spot ratios.
Question: What is the Accuracy of Infrared Thermometers?
Answer: As a conveniently accurate instrument, the infrared thermometer can quickly measure the temperature of any surface.
The IR thermometer has an accuracy specification that would depend on the individual model.
A lot of the infrared thermometers have a ± 2.0% measurement error.
If you want to have the readings by the IR thermometer’s accuracy dictated, you need to have a couple of other factors considered.
These factors include the target’s emissivity and the IR thermometer’s D:S ratio.
Question: Can it be Possible to Use the Infrared Thermometer Whenever You Are Cooking?
Answer: Since IR thermometers can only measure the temperature of a surface, they may not be accurate in gauging the food that you are cooking’s internal temperature.
Yet, it would be beneficial to have the infrared thermometer gun to measure your barbecue grill, skillet made of cast-iron, pan, or hot oil’s surface temperature.
Always remember that whenever you take the grill’s temperature, the temperature of the surface that you can see when you check the grate will be factored in.
If you need to have a reading that is accurate, you must have surface that is solid like a skillet or a plate made of cast iron placed on the grill then preheated for five to ten minutes.
After that, make sure that the surface is sprayed with some cooking oil so you can check the right emissivity then start taking the temp.
Question: How Can You Have an Infrared Thermometer Calibrated?
Answer: It is vital to regularly check your measuring instrument’s accuracy to make sure that you have a device that works properly.
A great way to have any infrared thermometer calibrated is to use the comparator cup for infrared.
The comparator cup can provide a base in solid black matte with a great rating for emissivity to see if your readings will be accurate.
You can have the cup used whenever you need to have the measurements compared from the calibrated reference thermometer and infrared thermometer.
As you can see, having an infrared thermometor around can be quite helpful in many different scenarios in any household, commercial kitchen, factory floor, or workshop.
It can quickly help measure the surface temperatures from a certain distance safely and accurately.
For professionals, among the highly recommended infrared thermometers is Fluke 62 MAX Plus.
It is a robust and accurate all-rounder that has a D:S ratio of 12:1, a broad range of measurement, dual lasers, and adjustable settings in emissivity that can help in pinpointing the measurement area’s edges.
Since it is built to be capable of withstanding a drop of three meters and has the IP54 rating for resistance against water and dust, you can depend on the Fluke 62 MAX Plus. in providing accurate measurements, even if you are on the dirtiest or toughest job site.
