Fluke VT04 visual infrared thermometer

The Fluke VT04 visual infrared thermometer has a built-in digital camera and thermal heat map overlay to bridge the gap between traditional IR thermometers and infrared cameras.

Compared with the Fluke VT02, the VT04 adds PyroBlend Plus, four-times sharper resolution and automatic alarm features - making it a suitable front-line troubleshooting tool for electrical, industrial maintenance, HVAC/R and automotive applications. It is fully automatic so issues can be detected instantly with no training required.

The device includes alarm features that are said to not have been seen before on entry-level infrared cameras for stubborn intermittent issues including: a hi-lo temperature alarm that flashes on the screen if the user-selected temperature is exceeded; a time-lapse image capture that can be set to capture images in 30 s to 1 h intervals; and an auto-monitor alarm that initiates image capture automatically after a temperature alarm has been triggered - letting users automatically capture images, even while the VT04 is unattended, using the universal tripod mount.

It displays and saves images as full digital, full infrared or in three blended modes (25, 50 and 75%) with a 40% wider field of view than the VT02. Markers pinpoint hot and cold spots indicating the hottest and coldest temperatures on the screen. A temperature reading is provided at the centre point. Images are saved to the included micro-SD card, eliminating the need to write down single or multiple measurements. The device also has a rechargeable li-ion battery.

Images from the device can be imported into the included SmartView analysis and reporting software.
