ALLOSUN Christmas Light Tester Non Contact Voltage Tester with Fuse Tester & Bulb Remover, AC Voltage Detector 12V-600V, Stepless Sensitivity Control Christmas Light Bulb Tester, Green

Voltage Testers

Buy on Amazon Find on eBay

All-in-One Functionality: This Christmas light tester combines a voltage pen and bulb detector, integrating features such as breakpoint location, live wire identification, bulb testing, and fuse inspection. It also includes a retractable bulb remover at the tip. Simply slide the switch forward to extend the remover. For a firmer grip, it's recommended to press the switch with your thumb during use.

Non-Contact AC Voltage Detection: Equipped with NCV technology, the Christmas light tester can detect AC voltages from 12V to 600V without physical contact. By bringing the tip close to a wire or appliance, it triggers audible and visual alerts when voltage is present. This helps prevent electric shock and allows for quick screening of outlets and electrical devices. When sensitivity is set to the lowest level, it can distinguish between live and neutral wires in a 220V socket.

Stepless Sensitivity Adjustment: Unlike products with limited sensitivity settings, this voltage tester pen features a scroll wheel for smooth, stepless sensitivity adjustment. You can easily find the ideal setting for any situation. For best results, start at the lowest sensitivity and gradually increase it until accurate detection is achieved.

Audio & Visual Alerts: When voltage is detected, a red LED at the tip flashes and a buzzer sounds. The intensity of the voltage is reflected in the frequency of both the light and sound alerts, providing an intuitive way to gauge electrical signal strength.

User-Friendly Design: Compact and lightweight, the Christmas light tester is easy to carry around. It includes a pocket clip on the back, allowing you to secure it to your pocket or tool bag for flexible use in various scenarios.

Power Supply: The light tester is powered by two 1.5V LR44 button cell batteries. For first-time use, remove the insulating strip from the battery compartment and ensure the batteries are installed with the correct polarity. After use, turn the switch to the "OFF" position to shut down the tester and prevent battery drain. Operating environment: 0°C to 40°C; relative humidity

Precautions: a. This Christmas light bulb tester is not suitable for LED lights. It can be used for incandescent bulbs, string Christmas lights, net Christmas lights, ice cream cone Christmas lights, etc. b. Due to factors such as sensitivity and detection distance, the tested object may still be live even if the Christmas light tester does not alarm. To avoid electric shock, do not touch any conductor with hands or skin. c. To avoid interference with detection results, do not use the tester in environments with strong electric fields.

Voltage Testers

Buy on Amazon Find on eBay

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. You CAN use it in sunlight, please kindly use your hand to shade the lights and it did the trick-- they will NOT be bright, but they ARE visible. Keep one on hand for regular fence line .

Tips Before Use: ALLOSUN fence tester can be matched to any animal control situation, offering both budget and design flexibility. You got to remember not the hits that touch the poly wire before you test. It is recommended to verify the tester's operation by measuring a known electric fence before use. Low voltages may be the issue that not being able to see the lights in bright sunshine.
