This circuit tester is a great way to test the capabilities of your outlets no matter where you are. Also measures AC outlet load handling capabilities to ensure safe and properly working outlets.

This meter also measures the voltage drop and line impedance to that outlet, great for knowing exactly the voltage at the outlet. The outlet tester functions also give the neutral to ground voltage and indicate open or reversed wiring. This is a great instrument for determining exact outlet quality.
