Last updated on September 17, 2022

The Fluke Corporation is at the forefront of technology innovation. Started in 1948, this company builds their products around maintenance, service, precision measurement, and quality control. If you are an engineer, technician, meteorologist, network professional, or medical device manufacturer, you will find a Fluke product designed to fulfill your needs.

For industrial technicians, utility inspectors, and maintenance personnel, the Fluke Ti400 is your best option. A thermal imager with exceptional imaging and analysis, this device is all about performance. It is one of the best thermal imaging cameras with high tech features so you can upgrade your old thermal tools to one that works perfectly. 

Thermal Imaging Technology

Fluke TI400 60HZ/FCA, TI400 Industrial Thermal Imager with Digital Multimeter A3001 FC IFLEX Kit

A 320 x 240- pixel thermal detector sits at the core of Fluke Ti400. It is a high-resolution imager which means greater clarity and all the critical details represented in an image. You will be able to use it in a wide variety of applications from facilities maintenance to building diagnostics, and even preventive maintenance. 

When you want to protect your investment, routine checkups of your HVAC system will be fast and straightforward with the Fluke Ti400. You just point and shoot to see the hottest and coldest parts of HVAC systems to know where you have air leaks. This way, you’ll never have to withstand working or living in a room with sweltering heat in the heart of summer. 

The Fluke Ti400 has a temperature range from -40F to 2,1920F. It is such a wide range that you cannot run out of areas where it will be useful. It is sensitive to within 0.05 degrees, enabling it to detect subtle changes in temperatures. Most industries will benefit from the accuracy and versatility of Fluke Ti400. 

LaserSharp Auto Focus:

The Fluke TI400 comes with a built-in laser. It provides sharp autofocus in difficult-to-reach areas. This feature makes it easy to do a reading around areas that have indistinct temperatures. If it is a leaking roof over a thick ceiling, you will be able to see where the actual leaks are coming from. 

The laser also allows focusing on a specific location. It accurately calculates the distance to a target, giving you the correct temperature measurements instead of being influenced by nearby objects.

IR-Fusion Technology

This technology has three major display modes. 

1. Picture-in-Picture Mode:

With an onboard, 5MP digital camera, the Fluke TI400 can capture visual photos and integrate them with a thermal image. With the help of IR-Fusion technology, it eliminates all the guesswork that surrounds a thermal image. 

This thermal imager can align infrared and digital pixels such that details are intricate and you can’t miss a thing. If you are looking at a pipe with numbers on it, you will be able to read those numbers and perhaps get information that helps pinpoint its location if other pipes surround it. 

This feature is just as important in identifying potential problems before they blow out of proportion requiring investments in new equipment that could cost thousands of dollars. 

The picture in picture mode can be a visual, thermal, or blended photo at the center of the image and the other parts are all of a digital photo.

2. Full-Screen Mode:

In this mode, you will see the center part of the picture in picture mode as a full-screen image. 

3. Color Alarm Mode:

If you have an area of interest on a target image this mode will help you. It shows infrared colors if the area you are focusing on exceeds a high or low previously set temperature. You can have hot and cold thresholds or absolute range color alarm mode.

Flexible Applications:

You don’t need to go looking for a separate thermal camera when you need to perform inspections around various projects. The Fluke Ti400 offers interchangeable lenses with either 2x or 4x wide angle and telephoto lenses. 

Fluke Connect System:

Teh Fluke Ti400 is an advanced thermal imager that allows you to transfer images to the connect system wirelessly from the camera. When you are on the field others can connect and see the photos, discuss it and make the right decisions when you are in the field. 

You can stream live images to have simultaneous maintenance records so members of your team can also give their input instead of going back to work on the conclusions. 

Rugged One-Handed Operation:

It is easy to see why most people love the Fluke Ti400. It requires only one hand to operate the functions. The device comes with a 3.5inch capacitive touchscreen. Using it in the field is quite simple because of its high sensitivity.

Since it is built for harsh environments, this thermal camera has a tough exterior featuring a robust display, integrated lens cover, recessed, protected lens, and an impact resistant housing that can withstand a 2-meter drop. Not to mention it has an exclusive, shock absorbing battery pack and an IP54 waterproof rating.

Its body is slim and light. The adjustable hand strap makes handling even more comfortable. 

IR-PhotoNotes and SmartView Software:

Apart from the blended thermal and digital images, Fluke TI400 gives you an easy method of analyzing your files. IR-PhotoNotes Annotation system allows you to capture three digital pictures per thermal image. This way, the files have more clarity, and you can document your problems easily. 

You can save voice recordings and annotations alongside the image file which helps in capturing the relevant details for later reference. 

Fluke analysis and reporting software; SmartView is perhaps the easiest way to manage findings. It allows exporting of images in JPG and BMP formats as well as creating custom reports that you can share with clients. 

Battery Life:

This thermal camera operates on a lithium-ion battery. It gives you a typical use of four hours. You also get an extra battery and external charger that will come in handy when working in the field. The battery only requires charging for 2 ½ hours which is pretty fast when you have to work continuously for hours. All you have to do is keep alternating the batteries, and your job will go smoothly. 


  • Rugged construction (tested for a 2-meter drop)
  • IR-Fusion technology provides different display modes
  • High infrared resolution at 320 x 240 pixels
  • 3.5-inch capacitive touchscreen
  • Intuitive analysis and reporting software
  • Wide angle and telephoto lens options
  • Wi-Fi connectivity to the Fluke Connect System
  • Built-in laser 


  • It is pricey, yet it does not have the highest thermal resolution in its class

Final Thoughts

If you are a busy technician, who needs a thermal camera that can do it all, the Fluke Ti400 will not feel like a splurge. It is reserved for professionals in manufacturing and maintenance industries where ignoring a procedure could cost you thousands of dollars in losses. 

Fluke Ti400 does not overlook any feature or make any compromises. It is a rugged and high-performing thermal imager that is worth the money.
