The Extech MA220 Compact Clamp Meter offers high accuracy for current measurements and its compact size allows measurements in tight locations. The MA220’s functions include AC/DC voltage (600 volts), AC/DC current (400 amps), Capacitance (100 µF), Frequency (150 kHz), Temperature (-58 to 1830 degrees F / -50 to 1000 degrees C), and Duty Cycle (0.5 to 99.0 percent). The MA220 also has a 4,000 count LCD display, data hold, auto zero on start up, as well as auto ranging and auto power off. This clamp meter has a 0.9-inch (23mm) jaw size that accommodates conductors up to 300 MCM. Comes with test leads, Type K bead wire temperature probe, case, two AAA batteries, and user guide.
