Key Features of this 3 Phase Motor Rotation Tester

Comprehensive 3-in-1 Functionality

Serves as a phase sequence indicator, an open-phase checker, and a motor rotation indicator, consolidating three essential tools into one compact unit.

Clear LED Indication

Bright, easy-to-read LEDs clearly display the phase sequence (L1, L2, L3), indicate a missing phase, and show the motor's rotational direction, eliminating guesswork.

Wide Measurement Range

Operates on a wide AC voltage range from 90V to 600V and a frequency range of 15Hz to 400Hz, making it suitable for a variety of commercial and industrial applications.

Motor Rotation Verification

As a dedicated motor phase rotation tester, it allows you to verify the motor’s running direction before it's connected to the system, preventing reverse operation and potential damage.

Safe and Reliable

With CE, UKCA, and cETLus certifications, this rotation meter electrical tool is built to high safety standards for secure operation in demanding environments.

Portable and User-Friendly

This lightweight and portable uni t phase rotation meter comes complete with heavy-duty alligator clips, making it perfect for on-site diagnostics.

Common Applications

This phase indicator meter is crucial for:

Motor & Pump Installation

Ensure correct rotation for 3-phase motors, pumps, fans, and compressors to avoid mechanical failure.

Electrical System Commissioning

Verify the correct electrical phase rotation at panels, circuits, and receptacles before powering up equipment.

Industrial Maintenance

Perform a quick phase sequence test on machinery, conveyor systems, and elevators during routine maintenance and troubleshooting.

HVAC System Setup

Confirm the correct phase sequence for air conditioning units and large ventilation systems to ensure proper functionality.
