Tronic Three Phase Rotation Indicator with LCD Display

Our review

The Tronic Three Phase Rotation Indicator is a rotary field instrument for checking the sequence of a three-phase supply. Instead of guessing whether L1, L2 and L3 are in the expected order, you connect the unit and read the phase rotation direction from its LCD screen, which also displays the three phases. That makes it useful for electricians, panel builders, maintenance technicians and anyone commissioning motors, pumps or other three-phase equipment where reversed rotation can cause damage or wasted time. Before buying, confirm the voltage range and connection style of the circuits you work on, since those details are not listed here, and check whether your work needs a contactless tester or a direct-contact indicator like this one. Compare it with basic phase sequence testers that rely on lamps or buzzers rather than a screen, and with multifunction installation testers that cost more but cover additional checks. The LCD readout is the main reason to choose this model over simpler indicators. It is available on Sokonia.
