The Extech CT70 AC circuit load tester quickly checks AC outlet load handling capabilities, with integrated outlet tester functionality. It measures AC voltage from 90.0 to 240 V, with additional frequency measurement from 45.0 to 65.0 Hz and peak line voltage up to 350.0 V.

As an AC load tester, the Extech CT70 features selectable loads of 12, 15 and 20 Amps, and measures both loaded and unloaded AC line voltage. Additional outlet testing functions include neutral to ground voltage, hot, neutral and ground impedance, GFCI trip time and current, and detection of open or reversed wiring faults.
