Why we love it
  • Integrated two-in-one functionality.
  • Safe non-contact voltage testing.
  • User-friendly with backlit screen.
Main Highlights
  • Integrated Voltage tester & Screwdriver - The VTS1000H includes a high-strength steel screwdriver at the tail. This Two-in-One tool is practical for wire checking and everyday electrical projects. It can differentiate between the live and neutral wires in cables and at the outlet, switch, and junction box. Easy to use for breakpoint tests. Safety rating: CAT IV 600V, CAT III 1000V
  • Non-Contact - This fully safe non-contact voltage tester features visual and audible alarms, measures AC voltage without physical contact using the NCV inductive probe by placing the tip near the terminal block, socket, or power line. NOTE: Readings can change based on distance, even when testing the same object
  • Dual Sensitivity Range - Features a high sensitivity detection range of 12-1000V, while the low sensitivity is 70-1000V, delivering more accurate and versatile measurements. You can adjust the appropriate sensitivity mode based on the voltage level of the object being tested by pressing the S button
  • Multiple & Intuitive Indication - When voltage is detected, the tip emits a red light, the screen backlight turns red, and an alarm sound is triggered. As the sensed voltage signal increases, or you get closer to the voltage source, the screen's analog bar, percentage value, and buzzer volume will increase.
  • User-Friendly Design - The Backlit Screen and Flashlight make it easy to use in a dark working area. Support Automatically turns off if there are no detected signals or user input within 5 minutes.
  • Lightweight & Portable - This pocket-size voltage tester includes a pen hook that can be carried in a toolbox or attached to clothes, making it a compact, portable tool that's useful on every job

Why we love it
  • Multiple alarms for safety.
  • Non-contact voltage detection.
  • Dual range for flexibility.
Main Highlights
  • 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
  • DUAL RANGE: Detects standard and low 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, and the percentage value can display the voltage signal intensity more intuitively
  • SECURITY LEVEL: IEC rated CAT III 1000V CAT IV 600V, Meets CE requirements; The electrical tester 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
  • COMPACT DESIGN: Bright LED flashlight for work in dim ares; Low-Power-Indicator when battery voltage is below 2.5V; Automatic Power Off after 5 minutes without operation or signal detection; Pocket-sized, pen hook allows you to carry it in your shirt pocket. We provide 36-Month after sale service, Please feel free to contact us if you have any concerns
