1、Measurement Range: Electric fence voltage tester quantify voltage on various metals, polyethylene wires, ropes, and tapes. Test fence lines, energizers, grounding systems, connection wires, and fence components. Neon lights display voltage from 2kV to 12kV, with a lifespan longer than ordinary flashings at 20,000 times. No need for battery. 2、Voltage Testing: Helps detect fence line faults. Insert the insulated handle to the ground and test the voltage levels on the fence line and fence controller. The fence tester shows a range of voltage readings, with brightness levels different from LED lights. Compact design lets you carry it in your pocket without taking up much space. 3、Exquisite Design: Waving patterns on the side for comfort. Matte finish on the smoothly ABS shell ensures a comfortable feel without harming your fingers. Matte finish is non glare. The ABS shell withstands cold weather but is not water proof. 4、8 Indicator Lights: The fence voltage tester features 8 neon indicator lights corresponding to detected voltages, making it easy to observe and locate faults in the fence line. Keep one handy for regular maintenance on the fence line. Specifically designed for low impedance and standard load fence controllers. 5、Easy to Use: Matches any animal control situation, offering flexibility in budget and design. Simply insert the copper probe into the ground and let the top hook make touch with the wire or tape.
