Description
Product overview: Fluke 355 True RMS 2000 A Clamp Meter
Versatile and rugged tools for applications with high currents
Confidently take reliable readings with the True RMS, Fluke 355 digital clamp meter the tool of choice for high current clamp-on amp meter measurement up to 2000 A. The extra-wide jaw easily clamps around large conductors, typically found in high-current applications. The extra rugged design and CAT IV 600 V, CAT III 1000 V ratings add an extra element of user protection when taking high-powered measurements.
Accurate peak measurements can be taken using the in-rush current mode, ideal for motors and inductive loads. The 355 also measures voltage and resistance, making this an ideal clamp meter for utilities, electrical contractors and industrial service technicians.
