Phase rotation testers are useful portable devices designed to check the direction of phase rotation in motorised machinery with three-phase supplies. These testers provide LED indication of both clockwise and anti-clockwise rotation. They are ideal for checking phase sequence in motors, pumps and air conditioning units. They can also be called phase sequence indicators, phase sequence meters of phase sequence testers.
