Fluke VT04A Visual IR Thermometer

Compact and intuitive, the VT04A and VT04 Visual IR Thermometers blend a visual image with a heat map overlay, to help quickly identify the location of issues.





For ultimate portability, that comes with a soft case and 4 AA batteries that are easy to change in the field. If you prefer a Li-ion rechargeable battery and a hard case

Do more with VT04. See more, find more, prove more.

See issues in context by blending the infrared heat map with the visual image, and get the detail you need by choosing one of five on screen blending modes.

Quickly identify the location of the issue – NEAR or FAR mode automatically aligns the visual and thermal lenses – even from as close as 15 cm (6 in).

Capture accurate temperature readings without taking your eyes off the screen. The center measurement box shows the exact area of temperature measurement. Fill the center box with your target and rest assured you’re not measuring the background.

These blended VT04 images show the breaker number that is hot. The on screen center box clearly outlines the temperature measurement area.

Find more. Identify intermittent problems.

Identify intermittent problems by monitoring equipment over time or get alerts when a temperature is outside the expected range with temperature alarms and automated monitoring features.

Instantly identify the hottest and coldest spots within the field of view with hot and cold markers.

Prove more. Optimize, analyze and report.

VT04 images can be taken in either .bmp or .is2 format. With an .is2 image, you can do the following in SmartView® software:

  • Optimize the visible and infrared heat map blending to any level
  • Add or remove the center marker and hot and cold markers
  • Change the emissivity and background temperature
  • Generate a professional report that can easily be edited
