REED R5044 Non-Contact Phase Rotation Tester


LEDs display motor rotation and phase status.

REED R5044 Offers

This motor rotation and 3-phase tester is capable of identifying phase orientation (clockwise or counter-clockwise). The R5044 features non-metal alligator clips that allow for safe non-contact measurements and includes back mounted magnets for easy measurement.


  • Non-contact voltage sensing alligator clips promote safety
  • Color-coded leads (red, black, blue) meet IEC 60446 standards
  • LEDs indicate phase orientation (clockwise or counter-clockwise) and whether each phase is live
  • Adjustable LED brightness allows for measurement in sunlight and lowly lit environments
  • Beeper sounds intermittently when detecting correct phase and continuously for a reversed phase
  • Durable housing with magnets frees hands and allows for easy measurement
  • Low battery indicator
