Description: brand new and high quality Feature: MS5900 three phase phase sequence tester, is used to detect the magnetic field direction, phase sequence rotation, motor rotation direction, etc. of three-phase system. It can detect the rotary field direction, non-contact rotary field indication, motor connection and magnetic field detection. There is no need to connect a test lead, just place the pointer over the motor and align it with the motor shaft to determine the direction of rotation of the motor. Fast and accurate measurement. Indicate phase orientation (Clockwise or anticlockwise). With simultaneous indications via LEDs, you can observe the station of the machine in real for time. Portable and compact design, easy and convenient to carry and use.
