• Can uses for people and surface objects
• Very accurate
• Gives temperatures from 32 °F to 212 °F

Cons

• More reliable with skin temperatures than object temperatures, however, you should buy this with the primary use to take temperatures of people

Temperature Range

The temperature range for most infrared thermometers ranges from about -40 °F to around 1000°F or around -48 °C to 550 °C. This can accurately measure anything from a cold freezer to a piping hot water heater.If you are looking to get an accurate human body temperature, most medical infrared thermometers will be in the range from 94 °F to 107 °F or about 35 °C to 42 °C. The average human body temperature should be around 98 °F or 36 °C

Brand

If you are looking for brand names in his industry, the ones I recommend are Fluke and Etekcity. They are both large multinational corporations that are innovative and provide high-quality products.

Accuracy

The definition of accuracy is how close the measurement comes to a particular value. All of these infrared thermometers are tested for accuracy by using an alternative temperature measuring devices to see if the values are similar. All the products on the list had performed well and accurately testing before they released it.

Power Source

The good thing about these thermometers is that they use either 9 Volt, AA, or AAA batteries. If you want to add longer battery life, purchase batteries that are designed for extra life like Energizer Ultimate. Another great thing is that most of these products come with batteries included.

Emissivity

I hope you people are up-to-date on your physics.  This concept has to do with thermal radiation, light, and temperature.

The definition emissivity is the ratio of the thermal radiation emitting from the surface of an object to the radiation from an ideal black surface at the same temperature (which is inside your IR thermometer).

This value is measured from 0-1.

A black body would have a value of 1, which means that it is a perfect emitter of heat energy. This includes water or ice.

Material with a value of 0 would be a thermal mirror, not admitting as much thermal radiation. This includes metals like silver or steel.

Infrared thermometers are useful because they can measure both the infrared and light radiation that is not visible to human eyes to give very accurate temperatures.

There are still things that can throw off accuracy.  The surface material can cause variation if the surface is reflecting a lot of light or shiny. Another problem if there is a cloud of mist or gas around the target that is measured.

Distance to Spot Ratio

This ratio is the distance to the measurement surface and the diameter of the temperature measurement area.

Given the example, if the ratio is 20:1, the diameter of the measurement area is 1/20 the distance to the object.

As the ratio gets smaller and smaller, the IR thermometer can sense temperatures with greater accuracy due to the reduced distance.

Warranty

The warranty is an important yet forgotten part of this purchase. All warranties are different, so make sure you check on this before you purchase. The average warranty could last from 1 month to 5 years. However, there are products like Kizen, which have lifetime warranties. More importantly, if you are concerned about having a good warranty, I suggest you buy from one of the larger companies like Fluke or Kizen.

Budget

The budget is probably the most important thing, as you do not want to break the bank just to measure temperature.  However, you must write down what you are looking for from an infrared thermometer. Make sure that whenever one you by, whenever price tag, checks off all the boxes on what you need.

If you are an electrician, please do not cheap out and buy an inferior product.  If you were a stay at home mother looking for a tool to help with her cooking, then a more affordable alternative would be okay.

Frequently Ask Question

How to Use an Infrared Thermometer?

There are generally 3 steps: 1) Turn on 2) Aim while staying at a safe distance 3) Press the trigger 4) Read the temperature

1.  Do not point the laser directly at others or in your own eyes

2.  Try not to use a laser on services that are shiny or reflecting a lot of light

3.  Make sure to measure it at a safe distance

What is an infrared thermometer used for cooking?

Cooking or baking usually requires something being at a specific temperature.  For food, an infrared thermometer can help you judge if something needs to stay cooking for longer or ready to come out.

Another use I have found is that it is perfect for calibrating your oven if you feel the temperatures are inconsistent.

How does an infrared thermometer work?

I hope you are ready for another physics lesson.  These devices work by using a lens to focus infrared light from an object onto a thermophile inside the machine.  As this thermophile absorbs the radiation from the object, it is pointed at it generates heat, which it converts to electricity.

This electricity is set to a mini processor inside the thermometer that determines the temperature of the object.

Is the infrared thermometer accurate?

Yes, it is. Because it is absorbing, visible light, and infrared light emitted from the object. This makes the temperatures it records much more accurate for surface temperatures.

Remember! These types of thermometers are not suitable for internal temperatures.

Is an Infrared thermometer safe?

Yes, they are very safe unless someone starts shining the laser in people’s eyes.

Will an infrared thermometer work on water?

Yes, an infrared thermometer will work on water. They are handy for obtaining the temperature of the surface of pools and other bodies of water, big or small.

What type of thermometer is most accurate?

If you are looking for accuracy, mercury thermometers are the most accurate type of thermometers.  However, they can be hard to read at times, and not to mention mercury is a toxic substance.

What are some uses of an infrared thermometer?

2. Home repairs

4. Checking the temperature of your bathwater, hot tub, or tea

Are infrared thermometers harmful to kids?

Yes, if children misuse them, it can cause eye damage.  If used safely, though, they pose no harm to children

Can I use a general-purpose infrared thermometer to measure human forehead temperature?

I would not recommend this. There are infrared thermometers made explicitly for medical purposes, and those are the most accurate ones.

What are the limitations of an infrared thermometer?

They are limited by the surface of the object.  If the surface is very shiny or reflective, it will make the temperature obtained less accurate. Also, gases like smoke or water vapor around the surface being measured can throw off the accuracy.

Are industrial type infrared thermometers safe to use on humans?

No, there are no side effects or damage it can cause to humans unless pointed at the eyes.

Can I use a non-contact infrared thermometer to check for fever?

Not only can you use it, but I would also highly recommend it.  Using one of the skin temperature infrared thermometers can help screen people with fevers to see if they need more medical care.  In these times, we must take every precaution

What emissivity setting is best, where do I scan and how do I convert skin temperature to internal temperature?

Emissivity settings depend on the surface object being measured.  In general, metals will have values closer to 0.Eeverything else has a value much closer to 1 like cement, water, ice, and stone. Remember, infrared thermometers cannot reliably tell you internal temperature only surface temperature.

Editor’s pick:

I have two editor’s picks.

The first one goes to the Fluke 561 HVAC Pro Infrared Thermometer.  To me, this is an outstanding outdoor infrared thermometer that anyone who needs to measure accurate temperature should have.

It has been approved by numerous regulation bodies. It has one of the most innovative lasers and lens technology apparatus.  It has a great battery life, reasonable price tag, and very easy to use. What is there not to love.

For human body temperatures, my pick is the Digital Infrared Forehead Thermometer No-Touch Thermometer from JUNWER.  This super affordable product is advantageous in the virus pandemic we are living in. You can take the temperature quietly and quickly with this fantastic tool. It incredibly accurate as the values only show a variation of .1 degrees Fahrenheit.

Along with practicing social distancing, we must pay attention to our health.

We must notice if we are developing any fatigue, muscle pain, and, more importantly, fever.

Conclusion

I hope our infrared thermometer review and buying guide helps to narrow down your choices.  Having an excellent infrared thermometer can help you with many tasks in the kitchen, outdoors, and even in the bathroom.

There are those specialized for outdoor tasks and those specialized for medical jobs. Many of them fall in between that spectrum.
