Hioki 3129 Non-Metal Contact Phase Detector, 600V AC Voltage, 45 to 60 Hz Frequency

Simple voltage detection and live wire check functions. Auto power-off function prevents inadvertent battery discharge. Internal safety feature indicates battery state by a blinking LED power lamp. Non-metallic contact for optimal safety The phase detector performs voltage phase detection just by clipping over insulated conductors. This unit can perform phase detection on insulated conductors, so it is safe to operate and usable practically anywhere. Voltage range AC70 to 600V, 50/60 Hz (sine wave, continuous input).
