Fluke i310s AC/DC Current Clamp Probe, 0.5 A to 400 A, BNC, 2 m Cable, Black/Yellow 2840309

Measure AC and DC current from 0.5 A to 400 A with a single clamp. The Fluke i310s delivers 1 mV/A output over a BNC connection, with a 32 mm jaw opening and a 2 m cable for flexible positioning.

Overview

The Fluke i310s is a current clamp probe designed for use with oscilloscopes and other instruments that accept a BNC input. It converts current into a voltage signal (1 mV per amp) for easy display and analysis. The clamp handles both AC and DC, with a frequency response up to 100 kHz for AC signals. The jaw opens to 32 mm, accommodating conductors up to that diameter. The probe is powered by a 9V alkaline battery and operates from -10 °C to 50 °C.

What stands out

• Wide current range: 0.5 A to 300 A AC RMS, 0.05 A to 400 A DC
• High bandwidth: DC to 100 kHz for accurate waveform capture
• Large jaw opening: 32 mm for clamping onto thick cables
• BNC connector with 2 m cable for easy connection to test equipment
• Safety rated CAT III 600V for use in industrial environments
