Fluke Flk-vt04: The Ultimate Guide – Full Specifications, Comparisons, Manuals, Troubleshooting, And Where To Buy
Fluke FLK-VT04 Information
The Fluke VT04 Visual IR Thermometer is a pocket-sized tool that combines visual and infrared imaging to help you see and measure temperature quickly and accurately. It features a 320 x 240 pixel color display that shows a live view of your target, along with an overlay of the infrared heat map. You can easily identify the exact location of potential problems by blending the two images at 0%, 25%, 50%, 75%, and 100% infrared with one button.
The VT04 also offers a number of other features to help you troubleshoot problems quickly and easily:
- Near and Far modes: The VT04 has two modes for measuring temperature: Near mode for close-up measurements (up to 15 cm/6 in.) and Far mode for longer distances (up to 600 cm/240 in.).

- Center box: The center box on the display shows the exact area of your target that is being measured, so you can be sure you're getting an accurate reading.
- Temperature alarms and automated monitoring: The VT04 can be set to alarm if the temperature of a target exceeds a specified threshold. You can also use the automated monitoring feature to track the temperature of a target over time and identify any problems that may be developing.
- Hot and cold markers: The VT04 can display hot and cold markers on the display to help you quickly identify the hottest and coldest spots in your field of view.
- Image storage: The VT04 can store images in .bmp or .is2 format. .bmp images can be opened with most image viewing software, while .is2 images can be opened with the Fluke SmartView® software, which allows you to further analyze and customize your images.
The VT04 is powered by four AA batteries (included) or an optional rechargeable lithium-ion battery. It comes with a soft case, a micro SD card, a micro SD card adapter, and a quick reference guide.
