Unique Features

This Dewalt imaging thermometer packs a great set of features in a robust housing.

Here’s what this thermometer kit has to offer.

Plastic Build

This Dewalt thermometer is made using premium plastic. It has a sturdy construction so that it lasts you for a long time. The plastic body easily withstands accidental falls and extreme temperature conditions.

Lightweight and Compact

With the plastic build, this thermometer is both lightweight, compact, and easily portable. You can easily carry it around in a backpack or the hard case without your hands tiring.

It is also quite ergonomic, so you can conveniently hold the tool in your hand while taking the readings.

Non-contact operation

Dewalt uses thermal imaging technology in this DCT416S1 thermometer to diagnose trouble spots.

By combining visual images on top of thermal images, this thermometer helps you get precise details of the spot, which helps the issue quickly.

And because it is a thermal imaging thermometer, this handy tool boasts contactless operation. This allows you to take the temperature reading from a certain distance, that too, with ease and accuracy. 

Now, you don’t need to get dangerously close to industrial equipment to measure the temperature.

Temperature Detection Range

One of the most prominent features of the DCT416S1 is its ability to measure over a wide range of temperatures.

It can detect temperatures from 14 °F to 480 °F, making it suitable for a range of applications, from checking pipes under the floor to measuring the temperature of hot industrial equipment.

And since it is highly sensitive, this thermometer compares different temperatures and provides repeated results to help you maintain quality standards in the workplace.

Adjustable Emissivity

Another great feature of the Dewalt imaging thermometer is the adjustable emissivity.

You can change the emissivity to tweak the thermal response and improve accuracy. Entering a measure of temperature helps you create accurate readings between adjacent heat sources. This provides enough contrast around an image and its background for accurate determinations.

You can adjust the emissivity from 0.1 to 1.0 with 0.01 increments.


Another cool feature in this thermometer is the tracking feature that locates both hot and cold spots on the screen.

A box floating around the screen with color zones represents both hot and cold points. This helps you quickly identify the spot you are looking at, speeding up the whole process.

Image Blending

An added feature in the DCT416S1 is the Image Blend that overlays the thermal image on top of the visual image. This overlaying helps you pinpoint issues with great ease.

Plus, you can even add more overlay until you get only the desired thermal image on the thermometer screen. 


The thermometer features a large 2.2-inch color display that helps you read the results with ease. The screen has different palettes representing different surfaces' temperatures, so you can easily differentiate hot spots from cold ones.

Another good thing is the wide 20° field of view that lets you take a clear, big image. This saves you from the trouble of taking too many shots of the same surface, saving both your time and energy.

Data Storage

The Dewalt thermometer allows you to record images and then store them on an SD card. You can store every image, be it thermal, visual, or blended, for later use and analysis.

Report Writing Software

Dewalt makes documentation simple for you with the Report Writing software.

It allows you to transfer data and images from the thermometer to your laptop or other devices for quick presentation to clients.

This proves really helpful in energy audits, electrical inspections, preventative maintenance, and even insurance claims to present the findings quickly and easily.

You can download the software directly from Dewalt's website.


Apart from being extremely functional, the DCT416S1 is quite user-friendly. It feels good in the hand and features only five keys to help you easily select the function.

Plus, with its contactless functionality, you can just aim this thermometer at the surface, press the button, and leave the rest to it.

Battery Life

The Dewalt thermometer uses 1 Lithium-ion battery that provides a run time of up to 5 times. Those who use a thermal imaging thermometer for a few minutes each day can easily expect the battery to last for a week.

The kit also includes a fast charger that takes just 40 minutes to fully charge the battery. You can also replace it with a new battery once it has outlasted its usefulness.


You get a micro SD card, 12V MAX Li-ion battery, a fast charger, and a kit box in addition to the DCT416S1 thermal imaging thermometer in the package.

Issues & Concerns

This thermometer stores the data on a micro SD card that you can only transfer to your laptop using the Report Writing software. It does not feature any external connectivity like Bluetooth or Wi-Fi, which limits data sharing.

Care and Maintenance

Proper maintenance and care are extremely important to maintain the durability and accuracy of the Dewalt thermometer.

Here are some tips to keep in mind:

  • Hold the thermometer with an excellent grip to avoid accidental falls.
  • Make sure to clean the thermometer with a soft cloth after every use.
  • Recharge the battery using the charger available in the kit every time it runs out.
  • Store the thermometer in the hard case when not in use.
  • Dust, debris, and moisture can affect the tool's accuracy, so try to keep them away.


The DCT416S1 thermometer comes with a limited 3-year warranty that covers manufacturer defects. The company provides free repair and service for the first year under regular everyday use of the device.

It also comes with a 90-day money-back guarantee, so you can return it if it does not perform up to your expectations.
