Phase Rotation Meters & Motor Testers

Electrical professionals who work on three-phase motors can use our motor testers to confirm rotation and/or wiring phase sequence. We stock a full selection of phase rotation instruments that help to protect motors or motor-powered systems. Our devices allow users to quickly and accurately detect sequence and check its status reliably. Motor testing equipment built by leading manufacturers, from Megger to Extech, can determine the orientation of each phase and issue “live” alerts.



Buy Calibrated Phase Rotation Meters Only From Transcat

Because Transcat operates dozens of ISO 17025 Accredited Calibration Labs across the United States and Canada, we are uniquely positioned to offer new instrument calibration services on most of the items we distribute. If your quality system requires that your instruments have a valid calibration certificate at all times, take advantage of our electrical calibration services so that your instrument arrives ready to be put into use.


Simply add calibration to your order on the product page or checkout screen.



Comparing Phase Rotation Meters

Transcat offers phase rotation meters for the field and the plant. Our testers mean you avoid connections that lead to improper motor shaft rotation. Within our motor and 3-Phase Rotation testing selection, we offer multifunctional instruments that perform open phase indication, motor rotation indication, and phase rotation sequence. We also have non-contact phase detectors designed for enhanced safety. When ordering phase rotation and motor rotation meters, you should determine if the following elements meet your application requirements: design (rotary, digital, non-contact), input voltage, frequency type, indication methods (visual and/or audible), test leads, and jaw size.


Fluke, Hioki SPM, Megger and Extech are brands that help installers achieve correct three-phase connections. Order a 3-phase rotation indicator that delivers high-voltage capability for industrial applications, or choose a device that tests up to 690VAC and displays graphical phase orientation on an easy-to-see LCD. We have the ideal tools for troubleshooting and maintaining ac/dc electric motors, generators or transformers. The Fluke 9040 is a high voltage rotary field indicator with an LCD display. In addition, it can verify 3-phase receptacle wiring and phase sequencing.
