The Greenlee TR-12A is a non-contact voltage detector designed to identify voltage in tamper-resistant and conventional fifteen amp and twenty amp, one hundred twenty volt outlets. This voltage tester features a patented automatic self-test to ensure the integrity of the device. When voltage is present, bright LEDs will illuminate and an audible alarm will alert the user. The design includes a silent mode to accommodate environments that require quiet operation.
Use this voltage detector to check for voltage in outlets, lighting fixtures, circuit breakers, wires, and cables, as well as to locate breaks in wires. It conserves battery life by turning off after five minutes of inactivity, and a low battery indicator alerts users when it is time for a battery replacement.
