Review: Handy little gadget - Perfect. Works a treat and comes with a nice led light for dark spaces. I used to identify live feed, isolate electricity at fuse box and re check. I always double check with a multi meter before commencing work.
Review: Great tester for someone who is in the know - I received a similar voltage stick as this,CEF (UK)was the supplier, same circuitry etc, the unit is brilliant, with some knowledge, the unit shows on a bar or two ghost potential, mutual inductance etc, when on a live cable, like right next to the probe, it's red, for example on a three core flex, line, neutral and earth aka ground, the probe can be rotated around the circular flex and live can be located or neutral, even though it's very close to each other, used so many times it's simply practice to quickly test, so on a closely connected neutral and line it's child's play, The meter scale from yellow to red is really useful, as it's not a binary light up and sound OR not, relying very much on the tester to determine, but the accurate scale of (if memory serves) four yellow LEDs to two red leaves room for knowledge, intuition on experience, a quick rule of thumb, one or two yellow, ghost or residual or mutual/ inductance voltage, 3 or more yellow, neutral and finally one or two red, live, it varies one either way for type of circuit / equipment or situation, but the rule of thumb is like 95% spot on, I am a fluke,megger, metrowatt, kewtech, etc guy, but this voltage stick for a passive device is brilliant, the more you use it, then you just know how its nuances are, Invaluable and ability to create a higher resolution from the circuit dependent binary of live or not, sound and light up or not, just proves again, cost is no metric for quality or performance, Make sure if your meter is in reserve in a toolbox or in storage, REMOVE THE BATTERIES! batteries leak and knacker the meter, had a Klein pen voltage stick ruined by a leaking Duracell battery, fixed down to component level, but it's a non serviceable unit, so makes a mess getting into the gubbins,

## Features

- 【CE CAT III600V RoHS Certificate Voltage Tester】 Neoteck professional AC voltage detector is safely double insulated. High Voltage Alert to warn you of voltage above 90V, the screen turn red and the safety symbol on the screen shines, perfectly suitable for DIY'ers, hobbyists and homeowners, which helps you make the First and the Most Important Safety Check.( Note Please: Not Suitable for Christmas Light Testing)
- 【Dual Range Electrical Tester】The 2022 upgraded circuit tester’s default mode is 48-1000V(Low Sensitivity), press the ’’S’’ to switch to 12-1000V(High Sensitivity), which can meet standard and low voltage (12-1000V AC / 48-1000V AC) for more sensitive and flexible measurements. Also, it is easier to identify live and null wire when the wires are neighbouring.
- 【Non-Contact Voltage Tester with LCD Display】With NCV inductive probe for AC voltage; just place the tip near a terminal strip, outlet, or supply cord, which can tell live and null wire without safety problem. When the buzzer alarms slowly, light flashes slowly and LCD shows green, it is Null Wire. While the the buzzer alarms quickly, light flashes quickly and LCD shows red, it is live Wire.

A: Yes, you can test your low voltage landscaping lights with your inquired voltage tester. (Note Please: DC powered landscaping lights is NOT supported)

**Q: Will this work on Christmas lights?**
A: It can test Christmas lights whose voltage is higher than 12V AC. For Christmas tree lights, we suggest a 'lower-wattage' type of detector. (Note Please: Not Suitable for DC Powered Christmas Light Testing)

**Q: Does this tester have a beeping sound when detecting voltage?**
A: YES! The Neoteck Non-Contact Voltage Tester DOES BEEP when voltage is detected! The beeping is very convenient to have when sticking the tester in a space where one has a hard time seeing the light-indicator.

**Q: I want to test the voltage for an outlet. Will this product tell me the voltage?**
A: It will only indicate if the voltage is present or not. No indication of how much voltage.
