The best overall clamp in Fluke's 320 series, the 325 builds upon the functionality and abilities of the Fluke 323 and Fluke 324 to offer a comprehensive measurement solution for electricians and engineers.
This clamp meter's jaws are able to open to a maximum diameter of 30mm, catering for conductors up to 600MCM. Once clamped around a conductor, it can test AC and DC current up to 400A.
Fluke's 325 clamp meter is also designed for use with other basic electrical measurements; it can test AC/DC voltage to 600V, resistance up to 40kΩ and also tests temperature, capacitance and frequency.
A true RMS clamp meter, the 325 ensures that accuracy is maintained even when testing AC voltage or current on irregular waveforms. Additional features of the instrument include a large size, backlit screen for use in poor lighting conditions, a data hold button which freezes a value on the screen.
