Analog voltage detector (two-pole) for safe voltage testing of direct and alternating voltages from 12 to 1000 V AC/DC. Indispensable when working on electric/hybrid vehicles to test whether the isolated areas of the high-voltage system are voltage-free. The following tests can also be performed with this tool. Rotating field direction test, single-pole external conductor test (phase), polarity test, low/high voltage test. Switchable vibration alarm in the test handle for safe voltage detection. The voltage detector is designed with a robust, impact-resistant round housing (rubberized grip surface).
