The Fluke 279FC/iFlex Wireless True RMS Thermal Multimeter combines full-featured digital multimetry with integrated thermal imaging for dual-function electrical troubleshooting. Engineers and technicians gain the ability to detect thermal anomalies, measure electrical parameters, and validate system performance from a safe distance. The 80 x 60 pixel infrared imager covers -10°C to 200°C with <200 mK thermal sensitivity. Wireless Fluke Connect capability enables smartphone data transfer and reporting; iFlex flexible current probe compatibility extends AC current measurement to 2500 A in confined spaces.
