EXTECH CT70 Electrical Load Tester

The Extech CT70 offers a versatile range of features for electrical testing, including selectable loads of 12 A, 15 A, and 20 A. It measures both loaded and unloaded AC line voltage, calculates and displays the percentage voltage drop and line impedance, and displays peak line voltage and frequency. The device also measures neutral-to-ground voltage, as well as impedance for hot, neutral, and ground connections. Additionally, it provides GFCI trip time and trip current measurements and can identify open or reversed wiring conditions.
