Wskaźnik napięcia VT-20

The VT 20 single-pole voltage detector of direct and alternating current enables for save, easy and exact checking a voltage presence in circuits and electrical arrangements. The VT 20 voltage detector is equipped with internal operation test arrangement supplied with 1.5 V, 2 A battery. It makes possible to check alternating voltage presence by contact method in the range 70 – 250 V and direct current by contact-less method in the range to 250 V, and also polarity in the range 1.5 to 36 V. The VT-20 indicator enables also to detect attendance of: high voltage in ignition systems, transformers, incorrect connections in electrical circuits and earthing of electric systems, live cables and conductors inside of walls, TV and computers’ screens electrostatic radiations and microwave penetration in microwave oven.
The indicator can be used in the range of temperatures from –10 °C to +50 °C both in indoor end outdoor conditions.
