Klein Tools NCVT5KIT: Dual-Range Non-Contact Voltage Tester with Laser Pointer & GFCI Receptacle Tester

Overview

Meet a compact, field-ready testing kit built for clarity and safety. The NCVT-5A non-contact voltage tester automatically detects AC voltage and signals readiness with a bright green LED, while flashing red or blue and emitting an audible cue when voltage is present. The RT210 GFCI receptacle tester helps diagnose common wiring problems in standard and GFCI outlets, enabling faster troubleshooting on the job.

Designed for professionals and serious enthusiasts, this complete kit pairs two trusted Klein Tools testers with practical battery power and clear instructions, all packaged for easy transport to service calls or DIY projects.

Key features

• Dual-range voltage detection: 12 to 1000V AC for low- to standard-voltage tasks
• Integrated laser pointer to identify targets from a distance
• Bright green power indicator with red/blue alerts when voltage is detected
• Auto-power off to save battery life during quiet periods on site
• RT210 GFCI tester checks for wiring issues in both standard and GFCI receptacles
• Complete kit with detailed instructions and all required batteries

Practical use scenarios

Use the NCVT-5A to verify the presence of voltage without making contact, such as while moving between cables, switches, or outlets. The laser pointer helps you aim toward a distant fixture or electrical box, reducing guesswork in tight spaces. The RT210 assists with common receptacle problems, from miswirings to testable fault conditions, supporting safer, more efficient troubleshooting.

In real-world service calls, the compact design and battery-saving features mean you can carry the kit in a tool bag and rely on quick-start instructions to get underway without delay. The combination of a non-contact tester and a receptacle tester covers both identification and verification tasks, helping you work with more confidence on residential, commercial, or industrial projects.
