The Sonel phase sequence testers are a proven measuring tool, whose main task is to control 3-phase electrical installations. Phase sequence tester signals compatible or opposite connection. The phase rotation meters are suitable for a wide range of phase-to-phase voltages (operating range is from 35 to 690 V, frequency from 10 to 70 Hz) in distribution circuits. The device signals compatible or opposite connections in the electrical installation and, in addition, indicates the symmetry of voltages in each phase. The Sonel TKF-12L is characterised by a simple and ergonomic design. Enclosed in a robust and sealed IP 42 casing, the tester ensures high durability and resistance to damage. The measuring instrument guarantees efficient operation in a wide temperature range from -10°C to +45°C. Double insulation according to EN 61010-1 ensures a high level of safety during testing.
