• Product Description

    Dual sensitivity

    Heartbeat - green LED indicates that the unit is on and working correctly

    Red LED indicates presence of voltage

    Audible tone also indicates the presence of voltage

    Unique dual sensitive non-contact voltage detector - just press and hold the desensitising button and you can differentiate between live and earthed cables approximately 10mm apart.

    An ideal addition to any electrician's toolkit, this Kewtech voltage detector instantly alerts the user to the presence of voltage from 90-600V AC without the need to make contact with a system.

    Uniquely designed, the Kewstick Duo is dual-sensitivity, including a desensitising button that can be used to differentiate between live and earthed cables 18mm apart. When voltage is detected using this voltage detection pen a red LED light will shine on the tip of the Duo and an audible buzzing noise will sound. A green LED and a separate audible tone also show the user that the tester is still working correctly when powered on.

    This voltage detector is CAT IV rated and pocket-sized for easy transportation/storage.
