12 Volt Probe Tester Plus (CRS721-2)

Upgrade your diagnostic capabilities with the 12 Volt Probe Tester Plus (CRS721-2)—the enhanced version that goes beyond basic voltage detection. This intelligent tester combines dual red LEDs with an audible buzzer to confirm 12-volt presence across your flat tape runs. Simply insert both pins into the copper conductors, and the tester instantly reveals whether you're working with AC or DC current. With DC circuits, the illuminated LED pinpoints the positive lead, eliminating guesswork. The simultaneous light and sound feedback ensures you never miss a voltage reading, making troubleshooting faster and more reliable than standard single-indicator models.
