BeGrit SW-8431 Non Contact Voltage Detector Volt Pen Electrical Tools Tester with LED Flashlight

The BeGrit Non-Contact Voltage Tester applicable for electricians, maintenance, service, safety personnel can quickly test for energized circuits and defective grounds on the factory floor, in the shop.
Non-contact test.
Breakpoint detect.
Test range: 90V-1000V AC.
Power supply: 2 x 1.5V AAA battery (Battery Not Included)
Product size: 5.83 x 0.67 x 1 inches
Product weight: about 0.8oz (without battery)

When no electric field signal is detected, tester is with green LED, it will automatically turn off in 5 minutes.
2. When detect voltage, tester tip sounds with red LED; when electric field becomes stronger, tester is with faster sound. Even the zero line and wire line are close, it is easy to distinguish.
3. Detect radiation intensity of electric field. When detect radiation, tester tip LED changes from green to red, and sounds
4. Breakpoint detect: two sides of the breakpoint have different radiation intensity, the difference can make tester emit different frequency sound. With obvious sound difference, user can find the breakpoint location. (Prerequisite: the line with breakpoint must be located on wire line, test along the surface of the line.)
