Extech MA220
400A AC/DC Clamp Meter
The Extech MA220 AC/DC Clamp Meter offers high accuracy current measurements and a compact size for measuring in tight locations. The MA220's functions include AC/DC voltage and current (600 V/400 A), capacitance (100 µF), frequency (150 kHz), temperature (-50°C to 1000°C/-58°F to 1830°F), and duty cycle (0.5% to 99.0%). It also has a 4,000 count LCD display, data hold, and auto zero on start up, as well as auto ranging and auto power off functions. This clamp meter has a 23 mm (0.9 in) 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.
