Professional Cordless Circuit Tester

The GTC CT8002 is a solid-state voltmeter designed for 3-28V DC systems in cars, trucks, motorcycles, boats and RVs. It draws only 20 micro-amps, making it safe for sensitive ECMs, sensors and airbag circuits. A single AA alkaline battery powers the unit and is included in the package.

Rugged Stainless Steel Build

The tester measures 7.5 x 3.5 x 1 inches and weighs 0.15 pounds, fitting easily in a tool pouch. Its cordless design eliminates the need for a ground wire or clip, while the V-groove accessory aids piercing and safe carrying. LED light, audible tone and vibration give three-way confirmation of voltage presence.

Replaces Traditional Incandescent Test Lights

Technicians moving from lamp-style probes gain 10000 times lower current draw, removing the risk of damaging modern vehicle electronics. The jump is worth it whenever a diagnostic routine involves computer-controlled systems or when a ground point is inconvenient or unavailable.
