Sonel TKF-12 – Phase Sequence Tester

The ergonomic phase sequence tester Sonel TKF-12 is a proven measuring tool, whose main task is to control 3-phase electrical installations. Phase sequence tester signals compatible or opposite connection, additionally it also shows the symmetry of voltages in individual phases. The instrument is suitable for a wide range of phase-to-phase voltages (operating range is 120 to 690 V, frequency 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. Due to its attractive price, versatility and ease of use, the instrument can be recommended to any electrician and not only. Sonel TKF-12 is characterised by a simple and ergonomic design. Enclosed in a robust and sealed IP42 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.
