Klein Tools RT250 GFCI Outlet Tester with LCD Display — $16.00 (36% off)
Klein Tools RT250 GFCI outlet tester with a backlit LCD that shows voltage, wiring faults and GFCI trip time — $16.00 at Amazon, 36% off the $24.97 regular price, straight price cut with no code.
36% offThe outlet tester electricians actually carry: plug the RT250 into any standard 3-wire 120V outlet and its big backlit LCD shows the line voltage, names the wiring fault, and — on GFCI outlets — measures how long the outlet takes to trip. It catches open-neutral and open-ground faults that basic testers miss, and an auto-hold keeps the reading on screen after you pull it out, which matters for outlets behind furniture. Amazon has it at $16.00 against a $24.97 regular price — a straight price cut, no code or coupon. Runs on 2 AAA batteries (included). Free shipping with Prime or on orders of $35 or more; Home Depot matches the $16.00 price.
