The FLUKE-279FC is true-rms thermal multimeter with integrated imager camera. This device helps to find, repair, validate and report many electrical issues quickly. Thermal imaging multimeter is a first line troubleshooting tool for electrical equipment that can check hot spots of high voltage equipment, transformers and detect heating of fuses, wires, insulators, connectors, splices and switches. Scanning with 279 FC's thermal imager reveals many electrical issues rapidly and from a safe distance. By combining two tools into one, thermal multimeter lightens the load and increases productivity. The 15 measurement functions including AC voltage with low-pass filter, DC voltage, resistance, continuity, capacitance, diode test, frequency. The large full colour LCD screen makes easier and clearer viewing of images and readings. It has 10hr+ rechargeable battery which keeps going all day long under normal conditions.
