New safety, non-contact voltage clamp meter
644 644 
Fluke’s 377 FC and Fluke 378 FC non-contact voltage True-RMS AC/DC clamp meters, to minimise the risk of electrical shock when electricians make live voltage measurements.
The Fluke 377FC and Fluke 378FC are the only clamp meters making accurate non-contact voltage measurements without test leads. Field-Sense™ technology makes testing faster and safer, without touching live conductors. Get accurate voltage and current measurements through the clamp jaw by clipping test leads to electrical ground, putting the clamp jaw around the conductor and reliable, accurate voltage and current values are displayed simultaneously.
