Unique Features

DeWalt has come a long way since its establishment. The brand never fails to impress its customers with its fine tools that tend to last on the job site. 

The same is the case with this Dewalt DCT416S1 thermal imager, which is packed with quality features to live up to customers' expectations. Let’s take a look at them.

Sturdy Build:

There is no point in investing in a thermal imager if it can't withstand tough situations of industrial and construction sites.

For this reason, the company has used premium plastic in the construction of this tool in order to ensure durability. 

The robust plastic build is resistant to corrosion and makes this thermal imager useful for multiple projects.

Design and Ergonomics:

With a robust body, this thermal imager has an amazing design that is not only functional but user-friendly as well. The handle fits like a glove in the hand.

Similarly, the large LCD display has a slight shroud to prevent glare production. Meanwhile, the incorporation of six buttons keeps all the functions at your fingertips.

Thanks to its lightweight body, you can use it for hours without any strain. On the front, there is a lens cover that ensures lens protection during storage.

Thermal Imaging Technology:

One of the most prominent features of this Dewalt product is the use of Dewalt’s own thermal imaging technology.

The unit is engineered to display both thermal and visual images on the screen for accurate diagnosis. 

To add on, the non-contact functionality makes the whole process even easier. All you need to do is point the unit against the surface and leave the rest to this device.

Image Blend:

An innovative feature included in this thermal imager is the Image Blend. This feature allows you to combine visual images on top of the thermal image to troubleshoot an issue quickly.

The overlay pinpoints the issue and offers precise details for easy diagnosis. 

Moreover, this feature helps professionals and technicians to document and transmit information in a more orderly manner.


As the name suggests, the incorporation of a tracker helps with the automatic identification of trouble spots.

The unit uses a standard blue-red-yellow color range to detect the cool and warm zones in the viewing area.

Temperature Range:

Ideally designed for industrial applications, this thermal imager features a temperature detection range from 14 degrees Fahrenheit to 480 degrees Fahrenheit.

This makes this tool extremely versatile and perfect for a number of applications. 

From overloaded circuits and looking at pipes under the floors to checking the temperature on hot industrial equipment, this thermal imager can cover a range of applications.  

This incredible tool can accurately measure all scenes of an image in one image, making it an ideal choice for experts looking for superior performance.

Moreover, its top-notch sensitivity lets you compare different temperatures to help achieve industrial goals.

Adjustable Emissivity:

This device lets you improve diagnostic accuracy with adjustable emissivity. You can adjust it with increments of 0.01.

The high-end contrast around the image allows a clear and precise diagnosis of the object.

Display and User-Friendly Interface:

The user experience with this imager becomes better with a clear and large 2.2-inch LCD display.

The colored screen on this thermal imager presents fine details of an image, helping you in the detection of hot and cold spots quickly and easily. 

Additionally, you don't have to click multiple pictures of a surface, thanks to the 20-degree field of view.

The menu is simple and easy to navigate, so you can make adjustments without any problem.

Micro SD Card:

One feature that makes this unit stand out to us is its ability to store the data on a micro SD card. You can store both visual and thermal snapshots for future use.

This allows you to capture and save data on-site, making the unit extremely practical for all-around usage.

In fact, you can transfer the pictures on another device and further analyze them using Dewalt's report writing software.


The Dewalt thermal imaging thermometer uses a 12 Max Lithium-ion battery to operate. You can expect a running time of up to five hours once the battery is fully charged.

The package also includes a fast charger that takes only 40 minutes to give you a full battery. 

Moreover, the battery is replaceable, so you can always go for a new one.

Issues & Concerns

There is no doubt that this Dewalt thermal imaging thermometer is equipped with advanced features; however, it has some limitations. These include:

Relatively Lower Resolution:

This unit does not boast the highest resolution as its competitors on the market. This is why it can’t work for all professional settings.

However, considering the price, the tool does a pretty good job. So, if you are new to thermal imaging, this Dewalt thermal imager would do fine.

No External Connectivity:

Another major concern about this thermal imager is the lack of Wi-Fi and Bluetooth connectivity. This makes the application a bit limited as you can’t transfer the data and adjust the settings with a single click.

Care and Maintenance

Though the Dewalt thermal imager is built nicely, proper care and maintenance can help you make the most of it in the long run. Here is what you can do to keep it accurate and functional for years.

  • Make sure to clean the unit thoroughly after each use.
  • Cover the lens with the lens cover to keep it safe from harsh elements.
  • Handle it properly with a stable grip to avoid accidental drops.
  • Always store the thermal imager in a cool and dry place when not in use.
  • Charge the battery immediately once it runs out.


While the Dewalt thermal imager is incorporated with a great set of features to make it functional, the company does not disappoint customers when it comes to warranty. 

The unit comes with a three-year warranty, which covers any technical and manufacturer fault.

Similarly, you can get the tool repaired for free during the first year under the one-year warranty.

However, this warranty does not work in case of improper use of the device.

That’s not all.

In case you don't like this product, the company offers a 90-day money-back guarantee to allow you to return the tool.
