Amprobe AMP-25 Mini Clamp Meter, 300 A AC/DC, True-RMS
Amprobe AMP-25 Mini Clamp Meter
Overview
The Amprobe AMP-25 Mini Clamp Meter packs professional clamp functionality into a pocket-sized 5.8-inch body. It measures AC and DC load current up to 300 A with 10 mA resolution on a 6000-count autoranging display, and its inrush function captures motor start-up current. A low-pass filter keeps readings usable on variable frequency drives, while true-rms processing delivers accuracy in noisy electrical environments.
Non-contact voltage (NCV) detection checks for live conductors without contact, and DCA zero plus data hold simplify day-to-day measurements. With a 25 mm (1.0 in) jaw opening, CAT III 600 V safety rating, 120 cm drop resistance and auto power off, the AMP-25 is built as a fast troubleshooting companion for commercial electricians and electrical contractors who need spot checks without carrying a full-size clamp.
Features
- True-rms AC/DC current measurement to 300 A with 10 mA resolution
- Low-pass filter for stable readings on variable frequency drives
- Inrush current function for motor start-up monitoring
- Non-contact voltage (NCV) detection for checking live circuits
- 6000-count autoranging display with data hold and DCA zero
- Pocket-sized at 5.8 in height with a 25 mm (1.0 in) jaw opening
- CAT III 600 V safety rated, drop-proof to 120 cm
- Auto power off after 20 minutes idle to preserve the LR44 batteries
Applications
- Spot checks of AC/DC load current on exposed wires in breaker panels
- Motor start-up (inrush) current monitoring on HVAC and pump systems
- Variable frequency drive troubleshooting using the low-pass filter
