ETCR1000D Non-contact Phase Sequence Detector with non-contact phase sequence detection, live line inspection, simple electrical inspection, fire line identification, default phase judgment, broken line location search and other functions, can clamp the wire with outer diameter Φ1.6mm～Φ16mm, When using, the insulation clamp can be directly clamped on the insulation skin of the live wire to test, no need to stripping off the wire or touching the exposed live wire of high voltage. The measurement result is dynamic display of LED, which is very clearness and directness, improves the safety and convenience of the test, and practically protects the personal safety of the operators.

The bottom plate of the instrument is equipped with magnets, the instrument can be attached to the metal shell of the equipment in the test, which makes the operation more convenient. The three clamps adopt 3 colors of the out shell,  which is more in line with the distinction of three-phase line and the national standard (GB681).
