Sperry Instruments GFCI Outlet Tester


Part of the Kono Gift Guide 2018

Handyman or not, this outlet tester is a useful gadget to have around. Proper grounds are important for PCs, audio equipment, and lab equipment — checking on your home’s wiring is a good idea for everyone. GFCI is also an important test point, as it is designed to protect you in bathrooms and kitchens (two places with lots of water and appliances).
