This GF211D dual-clamp digital phase angle meter eliminates the trouble of power cut and wire disconnection for on-site power inspection, greatly boosting field testing efficiency and cutting operational risks. Equipped with two matched 20A clamp CT sensors, it captures current signals directly by clamping single live wires, no circuit disassembly required.
Boasting dual fully isolated U1/U2 voltage channels up to 600V, it safely conducts synchronous testing of U-U, I-I and U-I phase difference within 0–360°. The 0.5-class high precision ensures reliable data for CT differential phase verification, transformer connection group inspection and energy meter wiring error checking. Its ultra-high current resolution supports tiny leakage current detection, serving dual purposes as a phase tester and leakage meter.
The lightweight 0.45kg handheld body with 3.5-inch backlight color LCD adapts to complex outdoor sites from -10°C to +50°C. It stores 500 groups of test records for later review, fully compliant with IEC61010 CAT III 600V safety standards for power plants, substation relay commissioning and industrial mining electrical maintenance.
