Features:
NKTECH NK5900 Motor and Phase Rotation Indicator is used to test magnetic field direction of 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 motor drive shaft. 
It is durable, reliable and light-weight handheld device, which is necessary tool for those who often install, repair or maintain three-phase system or motor.
