KAIWEETS Non-Contact Voltage Tester Pen – 12–1000V, LCD, Dual Range, CAT IV 1000V

Meet the KAIWEETS non-contact voltage tester pen, a compact tool designed to simplify electrical checks. With CAT IV 1000V safety rating, double insulation, and NCV technology, it detects live wires without direct contact, helping reduce the risk of electric shock during inspections. The device blends precise sensing with practical usability, making routine tests faster and safer for both DIY enthusiasts and professionals.

Real-time readings you can rely on

The tester uses an AC voltage NCV sensor to quickly identify live and neutral wires near outlets, switches, power cords, and circuit breakers. When voltage is detected, the probe lights red, a buzzer sounds, and the LCD displays a real-time signal strength with a percentage and a bar graph. This combination supports quick identification of open circuits, short circuits, or leakage paths, without guesswork.

Two ranges, tailored sensitivity

Choose between 12–1000V AC high range for general household wiring and 70–1000V AC low range for sensitive devices such as smart thermostats or irrigation controllers. The SENS button makes range switching effortless, helping reduce false alarms and interference in busy panels.

Clear alerts, at a glance

The high-definition LCD replaces traditional LEDs with clear numerical voltage readings, a live percentage, and a bar graph. The color cues and buzzer frequency increase as you approach a live source, delivering intuitive feedback without clutter or ambiguity.

• Red indicates live voltage; green indicates no current or low voltage.
• The audible alert grows louder and faster as the detected voltage rises.

Designed for on-the-go use

Beyond testing, the tool includes a bright built-in LED flashlight, helping you work in dark breaker panels, basements, or HVAC ducts. Its compact, pocket-friendly form with a clip fits easily in a pocket or tool belt. A 5-minute auto shut-off preserves energy, and a low-battery indicator keeps you informed. A 36-month warranty provides added reassurance for daily use in homes, workshops, and job sites.

Why it matters

With NCV technology and robust insulation, the KAIWEETS tester supports safer, more confident checks across a variety of settings. While not a medical device, it offers practical benefits for routine maintenance, troubleshooting, and quick safety checks in both home and professional environments.
