Amprobe AMP-25 – AC/DC TRMS Mini-Clamp
AC/DC TRMS Mini-Clamp
- Autoranging
- DCA zero and data hold
- Auto power off
- Large LCD backlit display
- Safety Rated CAT III 600 V
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 filter make this clamp stand tall next to clamps twice its size. With the AMP-25, you never have to sacrifice performance for size.
Troubleshoot electrical systems and measure AC/DC load current on exposed wires in a breaker panel.
Utilize the inrush current function for motor start-up monitoring.
The non-contact voltage (NCV) function checks for voltage presence.
Pocket-sized for quick and easy spot checks of electrical systems.
Convenience Without Compromise
