Voltage Testers

10 kV Voltage Tester is a high-voltage detection instrument used to verify the presence or absence of voltage in electrical systems rated up to 10,000 volts (10 kV).

New version of a neon tester The Sonel VT-3 pocket non-contact voltage indicator is a newer version of the popular neon tester. The instrument is characterised by its rich functionality as well as its lightness and ease of use. The device is designed to detect alternating voltage in cables and electrical equipment. The indicator has a basic detection range of 100...1000 V, but the lower threshold can be lowered to 12 V by pressing a special button. Coloured LEDs on the tip of the instrument indicate the operating mode and the level of voltage detected. Sonel VT-3 is a fully functional, professional instrument hidden in an inconspicuous form and compact dimensions. The highly durable IP 67 casing provides a high level of protection against various types of mechanical damage, drops and even against splashes of water. A particular advantage of this tool is its pocket-size design, which makes it extremely easy to store and transport. An additional advantage is the torch located on the front, which allows to illuminate the place of measurement. The instrument is also equipped with a rear torch for use when moving in poorly lit areas. The Sonel VT-3 voltage indicator facilitates measurements even in narrow and hard-to-reach places, where testing with a regular meter could prove impossible. Combining basic measurement functions, robust design and high levels of user comfort, the instrument is ideal for a wide range of applications, and is characterised by its trouble-free operation and competitive price. It is a supplementary piece of equipment for electrical specialists and, despite its small size, will certainly prove useful at times during work. Features two AC voltage detection ranges: 12 V / 100 ... 1000 V durable, two-composite housing waterproof with IP67 protection backlit tip, suitable for power sockets light and sound signalling when voltage is detected built-in LED flashlight ergonomic housing with the possibility of attaching to a belt for use in 50/60 Hz mains power supply: 2x AAA 1.5 V battery Application The VT-3 indicator is a new face of the classic neon voltage indicator. Lightweight, functional and easy to use, it is applied to detect AC voltage in cables and electrical equipment. The basic detection range is 100...1000 V. However, the lower threshold can be decreased to 12 V by pressing a special button. Colorful LEDs hidden in the device tip will inform about the operating mode and the level of detected voltage. Thanks to the improved design, the VT-3 maintains IP67 protection, and provides with durability and ergonomics. The built-in flashlight also plays an important role.
