“The RT250 was designed with unique features to make testing electrical outlets safer and easier,” said Sabrina Kalsi, product manager at Klein Tools. “The RT250 features auto-hold, which keeps the reading on the screen so that users can remove the tester to view the display.

An additional safety test includes the amount of time to trip a GFCI device, a feature not often found in GFCI testers at this price point.”
