Description

The Fluke 355 is a rugged and versatile True-RMS digital clamp meter engineered for high-current AC/DC applications. Its most prominent feature is the ability to reliably measure very high currents, up to 2000A DC and 1400A AC, making it an essential tool for utility workers, industrial service technicians, and electrical contractors. The meter’s extra-wide 58mm jaw easily accommodates large or multiple conductors. It also includes an inrush current mode to accurately capture motor start-up surges and a low-pass filter to ensure stable readings on noisy electrical loads. With a high safety rating of CAT IV 600V / CAT III 1000V, the Fluke 355 is a comprehensive and safe solution for demanding industrial and utility environments.

Key Features

High Current Measurement: Measures a wide range of currents, including 2000A AC + DC True-RMS, 1400A AC, and 2000A DC.
Extra-Large Jaw Capacity: A large 58 mm (2.3 in) jaw opening can easily clamp around large conductors or multiple cables.
Inrush Current Mode: Accurately and repeatedly captures and measures motor ‘power-on’ surge currents.
High Safety Rating: CAT IV 600 V and CAT III 1000 V ratings provide enhanced user protection in high-energy industrial environments.
Integrated Low-Pass Filter: Smooths out the readings from noisy loads to provide more stable and reliable measurements.
All-in-One Functionality: Measures voltage (up to 1000V DC / 600V AC), resistance, and frequency, making it a versatile troubleshooting tool.
Large Backlit Display: Ensures that readings are easily visible, even in poorly lit conditions.
