Designed for electricians and savvy homeowners, it meets IEC CAT III 1000V safety standards and offers enhanced sensitivity modes for versatile applications. Lightweight and pocket-friendly, it’s your essential tool for safe, precise, and efficient electrical diagnostics. ## Description Product Description Dual sensitivity HT100S provides two measurement ranges: high sensitivity mode (12-1000V) and high sensitivity mode (70-1000V). Sound, light and screen alerts The HT100S sends out three reminders according to the voltage level: beeps of different frequencies and red lights flashing, as well as percentages and bars on the screen. More intuitive percentage display You can judge the voltage intensity in the selected measurement range by percentage and bar. Red LED blinks If an AC voltage is present at the relevant measuring point, this is indicated visually by a red flashing LED. If there is no voltage at the measuring point, the display lights up green continuously. The meter will automatically turn off after 5 minutes of inactivity. 2 x AAA batteries Contains 2 AAA batteries. Low Powe Indicator When the battery voltage is lower than 2.5 volts, the display will display the symbol. The tester automatically shuts off when the battery voltage drops below 2.3 volts. LED Torch Work in a dark environment is not affected. Review: Ac/dc voltage tester HT100s - Excellent. Dead easy to use and gives a percentage. Great little device. This one is model HT100s gives bars as well as percentage readout. Review: Safe and simple to use. - Easy to read and a high accuracy of detection. With a built in torch to assist in dark areas during power outages. The unit comes with clear instructions and the build quality is excellent.

When the tip glows red and the pen beeps, you know there's voltage present. The live wire detector can automatically detect the live or neutral wire. Ideal for breakpoint Tests. Handy circuit tester for electricians, and homeowners. - Safety First: It will send out multiple alarms through sound and light. When the voltage is detected, the tip will send out red light and beep. When the higher the sensed voltage is, or the closer it is to the voltage source, it beeps at a higher frequency. At the same time, the screen will be red or green, red means the high voltage and live wire are detected, and green means the low voltage and null wire are detected. - Dual Range: Only detects AC voltage (12-1000V AC / 70-1000V AC) for more sensitive and flexible measurements. Press the S button to adjust sensitivity and adapt low range for doorbells, thermostats, irrigation wiring, etc; The NCV sensor automatically recognizes the voltage and displays it on the bar graph. - Security Level: IEC-rated CAT III 1000V, Meets CE requirements; The electrical tester is safely double-insulated. High Voltage Alert to warn you of voltage above 70V, the screen turn red, and the electric shock warning symbol is displayed on the screen. - Compact Size: Bright LED flashlight and backlit for work in dim areas; Auto Power Off after 5 minutes without operation or no signal detection; pen hook allows you to carry it in your shirt pocket.

The meter would register about "1 line high" near the wires BUT it would also cause the meter to blink the same on places on the wall where there was absolutely no elec wires! I did the test both using the regular setting and also the Supper Sensitive setting. So MAYBE it MIGHT give you some idea where the wires are, but doubtful since there are to many false readings to be sure. That said, this meter works great if you are taking readings without sheetrock blocking it. **Q: would you recommend this over other models and why? what do you NOT like about it? how accurate is it?** A: I like that it is louder than others, equally easy to use, and the price was good **Q: I believe a wire that goes from my speaker passenger side rear door is dead, would I be able to use this to test the wire to see if there's power?** A: You. Will need 12v tester **Q: Do i manually switch from "lo" to "hi"? pressing the green "sensitivity" button on mine does not switch to "hi".** A: Mine does not even turn on. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Ac/dc voltage tester HT100s *by A***N on 17 February 2026* Excellent. Dead easy to use and gives a percentage. Great little device. This one is model HT100s gives bars as well as percentage readout. ### ⭐⭐⭐⭐⭐ Safe and simple to use. *by A***. on 23 October 2025* Easy to read and a high accuracy of detection. With a built in torch to assist in dark areas during power outages. The unit comes with clear instructions and the build quality is excellent. A great tool that could save you from a nasty shock. ### ⭐⭐⭐⭐ Same as a mains tester screw driver *by G***M on 17 January 2024* A little slow and difficult to activate but once set up identifies live wires BUT only if you touch them. Seems to do little more than a mains tester screw driver with a beep and red flashing light. The LED spot light is useful. Good value for the money ## Frequently Bought Together - KAIWEETS Voltage Tester/Non-Contact Voltage Tester with Signal Percentage, Dual Range AC 12V/70V-1000V, Live/Null Wire Tester, Electrical Tester with LCD Display, Buzzer Alarm, Wire Breakpoint Finder - WGGE WG-015 Professional 8-inch Wire Stripper/wire crimping tool, Wire Cutter, Wire Crimper, Cable Stripper, Wiring Tools and Multi-Function Hand Tool. - DongChu Insulated Electrician Gloves 400V High Voltage Resistant Gloves --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.eg/products/549080274-kaiweets-ht100s-voltage-tester-dual-range-12v-1000v-70v-1000v](https://www.desertcart.com.eg/products/549080274-kaiweets-ht100s-voltage-tester-dual-range-12v-1000v-70v-1000v) --- *Product available on Desertcart Egypt* *Store origin: EG* *Last updated: 2026-07-06*
