  • Description+
  • Electronic AC/DC Voltage Tester

    Klein Tools ET40 is an Electronic AC/DC Voltage Tester. It features indicators for positive and negative DC polarity, and tests DC voltages as low as 1.5V. It tests AC voltages 12-240VAC. Excellent for checking, verifying or troubleshooting common residential electrical wiring in electrical outlets, light fixtures, doorbells and more. It operates on 2 x AAA batteries.

  • Features+
    • Electronic AC/DC Voltage Tester
    • Tests AC voltages from 12V to 240V AC at four useful levels aligned with commonly used residential voltages
    • Tests DC voltages from 1.5V to greater than 17 to 24V at four useful levels aligned with commonly used DC voltages
    • Bright LEDs illuminate to indicate the type and level of voltage detected
    • Built to withstand a 9.9-Foot (3 m) drop
    • Indicates polarity when measuring DC voltages
    • Powers off automatically after approximately 2 minutes of non-use to conserve battery life
    • CATIII 250V, Class 2, Double insulation
    • Ingress protection IP41 dust and water resistant
    • Built-in test lead holders on sides of tester
