Klein Non Contact Voltage Tester Pen, 50 1000V AC

About This Product

Ensure your pipe freeze protection and roof de-icing systems are powered, safe, and operating correctly without stripping wires or making direct contact. The Klein Tools Non-Contact Voltage Tester provides rapid, reliable detection of live voltage in self-regulating heat cables, power connection kits, cold leads, breaker panels, junction boxes, and standard outdoor outlets.

A high-visibility green LED lets you know the pen is active, switching instantly to a bright red light and sounding an audible alert the moment live AC voltage is detected. Compact, durable, and rated for tough job-site conditions, it’s a must-have tool for seasonal de-icing maintenance, pre-winter inspections, and winter freeze-protection troubleshooting.

Key Features & Highlights

• Ideal for Heat Trace Systems: Quickly verify live power to heat trace runs, thermostats, junction boxes, GFCI breakers, and connection tees without exposing live conductors.

• Dual Visual & Audible Alerts: High-intensity green LED confirms power-on status; instantly triggers a vibrant red LED and an audible beeper when voltage is present.

• Broad Voltage Detection Range: Detects standard 50 to 1000V AC power, covering standard 120V and 240V residential/commercial heat trace circuits.

• Job-Site Rugged: Built with 6.6 ft (2 m) drop protection to handle tough installs along ladders, rooftops, crawlspaces, and mechanical rooms.

• High Safety Rating: CAT IV 1000V rated for maximum user protection around service entrances and primary supply lines.

• Battery-Saving Auto Power-Off: Automatically shuts down after inactivity to preserve battery life during cold-weather storage.

• Pocket-Ready & Portable: Lightweight pen-style design featuring an integrated pocket clip so it’s always within reach on the job.

• Ready Right Out of the Box: Includes 2 x AAA 1.5V batteries and an operating manual.

Why You Need It for Heat Cable Installation & Maintenance:

• Pre-Season Testing: Quickly check that your roof and gutter de-icing cables or pipe heat tapes are energized before freezing temperatures hit.

• Fast Circuit Verification: Pinpoint whether a heating issue is caused by a tripped breaker/disconnected junction box before tearing into pipe insulation or roof clips.

• Safe Diagnostics: Confirms that power has been safely shut off before performing splices, end-seal repairs, or cable replacements.
