Pros

  • Combines a GFCI outlet/receptacle tester with a line splitter for amp draw measurement, making it a versatile tool.
  • Eliminates the need to split appliance cords for electrical measurements by allowing direct clamping on the hot wire.
  • Compatible with many popular clamp meters, including Klein CL220, Amprobe R Ultra, Sperry Snap 6, KAiWEETS KC604, and TESMEN TCM300A thanks to its 28mm x 20mm clamp diameter.
  • Provides quick and accurate info on wiring and GFCI status without removing receptacles.
  • Well made with durable, higuality materials and a solid, comfortable feel in hand.
  • Features 5 visual indicators to clearly communicate wiring status and GFCI functionality.
  • Made by a reputable company known for reliable test equipment, ensuring safety and accuracy.
  • Useful for both electricians and homeowners for quick testing and convenience on smaller jobs.
  • Enhances clamp meter functionality by enabling selective hot wire measurement, useful for surge detection.
  • Convenient threamp tester and line splitter in one compact device.

Cons

  • The clamp orientation can be slightly awkward when plugging into a wall outlet, often requiring a sideways viewing angle on the clamp meter display.
  • Best suited only for users who have compatible clamp meters that fit the 28mm x 20mm clamp opening, limiting its use if your clamp meter is a different size.
  • Primarily designed for convenience rather than heavy or continuous use, so it may not be ideal for large commercial applications.
  • Some users might find it a bit niche if they don’t already own a compatible clamp meter or don’t frequently test GFCI outlets.

Bottom Line

If you need a handy, reliable tool that combines GFCI testing with the ability to measure current via a clamp meter without physically splitting cords, the Triplett ET200 is a solid choice worth its $20 price tag. It's especially great for electricians and serious DIYers who already own compatible clamp meters and want an efficient, all-in-one tester. However, if you don’t have a clamp meter in the compatible size range or need a simpler outlet tester, you might want to look into dedicated GFCI testers or simpler receptacle testers that don’t rely on clamp meter compatibility for full functionality.
