With so many different options currently available, it can be difficult to determine what the best infrared thermometer gun is. We are here to make that determination easier for you. Not only will we tell you the features to consider when choosing an infrared thermometer gun, but we will also tell you all about the best option currently out there for you – the ThermoPro TP30 Digital Infrared Thermometer Gun.

Common Features of an Infrared Thermometer Explained!

1. Temperature Range and Resolution

Not all infrared thermometer guns work at the same temperature range. Some are designed to only be able to read colder temperatures, some operate well at medium temperatures, some handle heat well, and some cover a range of all of those.

You will want to pay special attention to a specific gun’s temperature range before purchasing, making sure that it is compatible with the job you will be using it for. If it doesn’t have the proper range and resolution capabilities, it isn’t going to be of any use to you.

2. Focus Spot Size and Distance

The focus spot size refers to the surface area – in diameter – an infrared thermometer will measure the temperature of. The distance, on the other hand, is how far away a certain target can be from the thermometer itself and still register. You will need to consider the work you will be doing when deciding if you need a gun that operates at a distance or only at close range.

3. Accuracy

Accuracy is probably the most important features to consider when dealing with infrared thermometer guns. The accuracy refers to how precise or exact the temperature reading is.

Obviously, you want the reading to be as accurate as possible so that the job you are doing remains accurate, as well. There are some situations in which an inaccurate temperature reading to could lead to dangerous results, so choosing a high-quality, accurate product you can rely on is important.

4. Emissivity

A temperature gun’s emissivity refers to the amount of infrared energy it can actually emit while being used. This number is typically measured on a scale from 0-1 and can be affected by the types of materials you are measuring to begin with.

Some thermometer guns allow you to adjust the emissivity level yourself between and during uses. This can be extremely helpful when trying to get a more sensitive or accurate reading.

5. Laser Sighting

Laser Sighting refers to whether or not a specific temperature gun emits an easy-to-see laser for more accurate aiming. Without laser sighting, you will simply have to point the gun in the direction of the target to be measured and eye it yourself. With laser sighting, however, you can place the laser precisely on the target, even if it’s far away.

6. Data Logging

A data logging thermometer gun allows you to store information as you collect it. The gun will save the date, time, and temperate of a certain object or area, making it incredibly easy to go back and compare next time you need to measure the same thing.

Alternatively, a thermometer without a data logging feature will display this information just once, directly after measuring, and not store it. Data logging is a convenient feature to have, but it isn’t necessary for everyone or all jobs done with an infrared thermometer gun.

7. Display Type

The thermometer gun’s display type will determine how information gets shows to you after a measurement is taken. If you are going to be using the infrared thermometer in poorly lit conditions where it might be hard to read, then you want to definitely consider an option with a clear, bright, backlit display and large numbering.

Features to Consider When Selecting an Infrared Thermometer Gun

Speed and Accuracy

When choosing your infrared thermometer, you want something that is going to give you as accurate a reading as possible while still working faster than other options.

An efficient thermometer will allow you to work at a more productive place while never having to worry about mistakes or oversights being made due to inaccurate temperature readings.

Range and Uses

You may very well be being an infrared thermometer gun for one very specific purpose. However, it is always beneficial to buy a product that can be used in a variety of different ways and in different circumstances. You never know when a new situation may sneak up on you when you wish your thermometer gun did more than what you bought it for!

Even in you only need your gun to measure a small range of temperatures or operate a close distance, you won’t be disappointed choosing an option with more capabilities then you think you’ll need right away. Generally speaking, the more range the thermometer has, the better quality it is going to be.

Ease of Use

Any product you buy is going to be completely useless to you if you can’t figure out how it works. You not only need to know its common uses of an infrared thermometer, but also need to know how it works. When choosing the best infrared thermometer gun, look for a product that is easy to learn and operate. Typically, you’ll want to look for an option with simple, easy-to-read control buttons and information clearly displayed on the screen.

Warranty Inclusion and Length

Always be sure to look into a product’s warranty before deciding to purchase. You are investing your own money into this thermometer gun, so you’ll want the peace of mind of knowing that you’re protected should anything go wrong. Defects happen, even in the best and highest quality products, but you shouldn’t be financially responsible for them.

Superior Features of ThermoPro TP30 Infrared Thermometer Gun

Highly Accurate

The ThermoPro TP30 features the latest thermopile sensor technology available, making it one of the most accurate infrared thermometers you can get your hands on. It provides temperature readings at an impressive accuracy of ±1.5%, so you won’t have to worry about double-checking your work or constantly wondering if the information you gathered was correct.

Allowing it to be even more accurate of a thermometer than it already is, the ThermoPro TP30’s accuracy is adjustable. The emissivity can be changed anywhere from 0.1 – 1.0 to account for different types of materials being measured. Not all infrared thermometers feature this ability.


The ThermoPro TP30 features an incredible response time of 500Ms, displaying all of the temperature information you need almost immediately after you point and shoot it in a given direction.

Even more impressively, this infrared thermometer has a distance spot ratio of 12:1, so it works just as fast even at greater distances.

Various Uses

There is no ned to what the ThermoPro T30 is capable of. It features an incredibly wide temperature range, allowing users to measure anything from -58°F – 1022°F (-50°C – 550°C) with ease. Very few things lie outside of that range, and so there isn’t a whole lot that this thermometer would be incapable of measuring.

No matter what you initially buy this product for, you will quickly find new and exciting ways to use it that you hadn’t thought of originally.
