The Fluke 353 True-RMS AC/DC Clamp Meter, 1400A AC, 2000A DC is the tool of choice for high current clamp-on amp meter measurements. The extra-wide jaw easily clamps around large conductors, typically found in high-current applications. The extra rugged design and CAT IV 600V, CAT III 1000V ratings add an extra element of user protection when taking high-powered measurements. The 353 takes accurate peak measurements using the in-rush current mode, which is ideal for motors and inductive loads.
