NEW FROM KLEIN TOOLS! ET40 & ET45 VOLTAGE TESTERS

Klein Tools Adds Two New Voltage Testers to Their Test & Measurement Line

Klein Tools’ ET40 and ET45 Voltage Testers were designed as simple, easy to use testers for checking, verifying or troubleshooting common residential electrical wiring and devices such as outlets, light fixtures, doorbells, batteries and more! Bright LED’s illuminate to indicate voltage levels detected. Convenient features on both models include four levels of voltage testing, built-in test lead holders (for attached leads) and convenient pocket clip for carrying.
