Extech MA250: 200A AC Clamp Meter + NCV

AC Clamp-on meter with Integrated Non-Contact Voltage Detector

The compact Extech MA250 200 amp AC/DC clamp meter offers maintenance technicians, electricians, and DIYers a test instrument that delivers a high level of features and value. In addition to a host of core multimeter and current measurement capabilities, it also features a built-in non-contact voltage (NCV) detector. The heart of the MA250 is a full-function digital multimeter. Measurement functions cover most types of troubleshooting over and above noninvasive current probe measurements: voltage, resistance, capacitance, frequency, duty cycle, diode and continuity tests. Even measure temperature with the supplied Type K bead wire temperature probe. MA250 comes with test leads, general-purpose Type K bead wire temperature probe, two AAA batteries, carrying case, user manual, and one-year limited warranty.
