MA410 – 400A AC Clamp Meter + NCV

The compact-sized Extech MA410 400 amp True RMS autoranging AC/DC clamp meter offers plant maintenance techs, electrical contractors, HVAC troubleshooter, 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 has a built-in, non-contact voltage (NCV) detector. The heart of the MA410 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 probe. Comes with test leads, general purpose Type K wire temperature probe, two AAA batteries, carrying case, user manual, and manufacturer’s one-year limited warranty.

  • AC Current, AC/DC Voltage, Resistance, Frequency, Capacitance, Temperature, Duty Cycle, Diode and Continuity
