The 400A Extech MA200 clamp meter, accurate to within ±2.5%, can be used as a basic AC current meter or upgraded to an AC/DC model (Extech MA220 clamp meter). The compact size, weighing only 7 oz., makes the handheld Extech MA200 clamp meter convenient for tight locations. Also, both models are CAT III-600V rated.

The Extech MA220 clamp meter model comes with several additional features: DC current measurement, one touch "auto zero," and capacitance, frequency, temperature and duty cycle.

The Extech MA200 / MA220 clamp meter comes complete with test leads, two AAA batteries, and a convenient carrying case. The 400A Extech MA220 clamp meter also includes a bead wire temperature probe.
