Extech PQ2071 1-/3-Phase 1000A True RMS AC Power Clamp Meter

The PQ2071 is built for demanding electrical diagnostics, energy audits, and system commissioning work. It functions not just as a high-range current clamp, but also as a full power meter, multimeter and AC-voltage detector. With a large 55 mm jaw opening it accommodates large conductors or bundled cables, and it supports current measurements up to 1000 A along with voltages to around 750 V AC. The instrument calculates and displays true power (kW), apparent power (kVA), reactive power (kVAR), and cumulative energy (kWh), as well as power factor and phase angle across one or three phases without re-clamping or changing test leads. It features a dual backlit LCD display, built-in non-contact voltage detector for quick field checks, a USB interface for data-logging to PC, storage for multiple data sets, and familiar clamp-meter functions like Min/Max, Data-Hold and auto-power-off. With its safety rating suitable for high-demand installations and robust build, the PQ2071 is a practical all-in-one tool for professionals who need to monitor power quality, verify efficiencies, and troubleshoot large electrical systems.

Features

• True RMS clamp-meter with current measurement up to 1000 A and voltage up to roughly 750 V AC.

• Measures single-phase and balanced three-phase systems: true power (kW), apparent power (kVA), reactive power (kVAR), and energy (kWh).

• Displays power factor and phase angle between current and voltage, giving deeper insight into system performance.

• Large 55 mm (≈2.16″) clamp jaw opening allows measurement of large conductors or cable bundles.

• Dual backlit LCD display (9999-count) with bar-graph, offering clear readability in field conditions.

• Built-in non-contact voltage detector with LED alert for quick verification of live conductors.

• Manual storage/recall capability for up to 99 data sets, plus Min/Max, Data-Hold and auto-power-off for convenience.

• USB interface for connection to PC and data-logging capability so data can be downloaded, archived or analysed further.

• Safety rated to CAT IV-600 V environments (with proper use) making it suitable for industrial and commercial power systems.

• Includes full power-analysis capability (true, apparent, reactive) making it far more than a simple current clamp — ideal for energy audits, motor/generator work and power-quality diagnostics.
