Klein Tools AC/DC Voltage Tester

The ET45 is designed as a simple, easy to use tester for checking, verifying or troubleshooting residential electrical wiring and devices such as outlets, light fixtures, doorbells, batteries and more. Its bright LED display illuminates to indicate voltage levels detected. This tester includes built in test lead holders (for attached leads) and a convenient pocket clip for carrying. The ET45 requires no batteries to operate, since it is powered by the source being tested. The test lead holders are spaced for testing tamper-resistant US style outlets.
