HT100s Voltage Tester/Non-Contact Voltage Tester and KT301T GFCI Outlet Tester with LCD Display

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 and the percentage value will be larger. At the same time, the screen will be red or green, red means high voltage and live wire are detected, green means low voltage and null wire are detected;
NON-CONTACT: With NCV inductive probe for AC voltage; Just place the tip near a terminal strip, outlet, or supply cord. 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 Test. Handy circuit tester for electricians, homeowners; Clear LCD Display & Bottom Indicators- Equipped with a vibrant color LCD display, this tester shows whether an outlet is wired correctly (green for good, orange for faults) and displays real-time voltage. Bottom indicator lights enhance visibility in dark or tight spaces. The intuitive design makes it easy to read wiring status and voltage at a glance.; Electrical Problem Checker- Designed for North American 3-wire 120V outlets with CAT II 135V safety certification. Quickly test outlet voltage and detect seven common wiring faults: Correct Wiring, Open Ground, Open Neutral, Missing Live, Live & Ground Reversed, and Live & Neutral Reversed, ensuring safe and reliable electrical connectio
