The Fluke 355 True RMS clamp meter is the tool of choice for high-current measurements up to 2000 A. It can reliably handle a wide range of high-current applications, with 2000 A AC + DC True RMS, 1400 A AC and 2000 A DC current ranges.

Its 58 mm (2.3 in) jaws easily clamp around large or multiple conductors typically found in high-current applications. The rugged industrial design, paired with CAT IV 600 V and CAT III 1000 V safety ratings, adds an extra layer of protection when taking high-powered measurements.

The built-in in-rush current mode enables accurate peak current measurements, ideal for motors and inductive loads. This function captures power-on surge current with high accuracy and repeatability.

The Fluke 355 True RMS clamp meter also features MIN, MAX and AVG functions for quick reading analysis, a large backlit display for easy visibility in low-light areas, and a HOLD feature to capture readings when the display cannot be viewed directly.

The Fluke 355 measures voltage (1000 V AC + DC True RMS, 600 V AC and 1000 V DC) and resistance (up to 400 kΩ), making it a highly versatile tool for utilities, electrical contractors and industrial service technicians. Resistance measurement, coupled with a continuity beeper, adds the convenience of a multimeter in a single compact tool.
