Amprobe AMP-25 Specifications

AMP-25 AC/DC TRMS Mini-Clamp

Convenience Without Compromise

Small size doesn’t mean small features. The Amprobe AMP-25 Mini-Clamp is pocket-sized, enabling quick and easy spot checks of electrical systems. With its rugged construction and CAT III 600V rating, the AMP-25 is a must-have professional troubleshooting tool for commercial electricians and electrical contractors.

The AMP-25 is designed to measure AC/DC load current and inrush current for motors.

Essential features like True-RMS, non-contact voltage and low pass lter make this clamp stand tall next to clamps twice its size. With the AMP-25, you never have to sacrice

performance for size.
