The Fluke T6-600 Electrical Tester with Field Sense™ technology enables quick and safe measurements in craned electrical boxes. This tester allows you to slide the open fork over a conductor without the need for test leads, making it easier to find safe metallic contact points. With a jaw opening of 17.8 mm, the T6-600 can work with wires up to AWG 4/0 (120 mm2). It can measure AC voltage, current, and frequency without touching a live wire, offering a variety of measurement options for troubleshooting. The tester can measure true rms voltage and current ranging from 0 to 200 A AC or 1 to 600 V AC or DC, and resistance from 1 Ω to 2000 Ω. The backlit display ensures visibility in dark environments, and the HOLD button allows you to keep your most recent measurement on the screen for easy viewing. Additionally, the T6-600 is compatible with the optional Fluke TPAK Magnetic Meter Hanger for convenient operation.
