The GFUVE GF211D is a lightweight handheld two-channel phase measuring instrument, tailored for reliable and speedy on-site electrical inspection tasks. Fitted with two clip-on current sensors, it realizes non-stop live line testing with no need to cut off circuits. It can precisely measure AC voltage, alternating current, phase difference, frequency, active power, reactive power as well as power factor.
Built with safe isolated input design, it adopts a 3.5-inch vivid color LCD screen for intuitive data reading. It boasts 0.5-level high measuring accuracy and can save up to 500 sets of test data. This device can easily distinguish inductive and capacitive loads, judge three-phase phase sequence, inspect transformer wiring status, confirm electric energy meter wiring correctness, and analyze phase relations of CT differential protection systems.
Lightweight at merely 0.45 kilograms and driven by rechargeable 9V lithium battery, this sturdy tester complies with IEC safety standards. It is widely applied in substation installation acceptance, daily power equipment maintenance, industrial electrical detection and on-site fault diagnosis for electric power, machinery manufacturing, petrochemical and other industries.
