Extech 380976-K 80A Single Phase/Three Phase 1000A AC Power Clamp Meter Kit helps you check power safely and quickly. It measures real, apparent and reactive power while showing power factor and phase so decisions are fast and clear. You can verify loads on single or three-phase systems, and you can confirm direction with a simple lead or lag view. The kit design keeps everything together so set-up is simple and repeatable.
Power analysis made clear
You get voltage tests that auto-select AC or DC and show frequency at the same time, so there is no need to switch ranges during checks. Horsepower readout supports motors on the shop floor and on site, so you can compare against nameplate values confidently. Phase angle in degrees helps you confirm correction or diagnose issues, and it stays readable while other values update.
Kit built for practical work
The clamp reads large currents with fine resolution for tracing load steps, and the microcurrent ranges handle sensitive control circuits without fuss. The included CAT IV lead set adds secure connections for live testing, and the large alligator clips make busbar work easier. A Type K temperature probe supports quick thermal spot checks before or after electrical tests.
This meter suits commissioning, fault-finding and maintenance. It switches smoothly between power, voltage, current, resistance, capacitance and frequency, and it keeps measurements stable for reliable notes. The carry case protects the set on the move, and the 9 V battery keeps you working through the day without tools for charging.
