Overview:
MS5900 Motor and Phase Rotation Indicator is used to test magnetic field direction of the three-phase system, phase rotation, motor rotation direction.
Without a need to link testing line, the motor rotation direction can be decided by placing this indicator above the motor and aligning it with a motor drive shaft.
It is durable, reliable and light-weight handheld device, which is a necessary tool for those who often install, repair or maintain the three-phase system or motor.
