Built for outdoor use, it operates within a wide temperature and humidity range, making it a must-have tool for proactive fence maintenance. ## Description ALLOSUN GK503B NEON Electric Fence Voltage Tester and Fault Finder Max 7 kV, NOT LED, Red - desertcart.com ## Features - Widely Application: The electric fence tester can only be used to test standard duty, low impedance electric fences. You can use it checking power on the electric fence around the garden, small enough to carry in a pocket. You have to hide it or put something over the top of it like that to see the light because in direct sunlight the neon light will not show up very well.The higher the voltage, the brighter the neon lamp. - Easy To Use: The electric fence voltage checker can test voltage levels on your fence line and fence controller,finding fence faults. Hook the metal loop on top to the wire, stick the probe in the earth. Just hang it on the fence and stick the probe in the ground under the fence. This product is only suitable for use in environments with temperatures ranging from 0 ℃ to 40 ℃ and relative humidity ≤ 80%; At the same time, the storage conditions of the equipment must meet the requirements of temperature -20 ° C~50 ° C and relative humidity ≤ 85%. - Neon Lamps, Not LED: The electric fence voltage tester, neon lamps indicates voltage levels from 0.6kv to 7kv (600 volts to 7000 volts). It uses neon bulbs, not LEDs to show voltage, neons are durable and can handle thousands of volts, much easier to read in shade or in evening light. - Dim Lights And Neon Principle: The electric fence testers have a pulse low voltage wire fence, make sure the wires are not touching anything metal by using plastic insulation to attach wires to your fence posts. The tester does not use batteries, and thus works on the principle of the fence high voltage exciting a neon bulb. As such, the light will never be bright, due to the technology of the bulbs.
