The Extech PRT200 is a non-contact phase sequence tester with an input voltage of 75-1000 VAC and a frequency range of 45-65 Hz. This tester has LEDs that indicate whether each phase is live and its orientation; a beeper sounds occasionally when the right phase is detected and continually if the phase is reversed. An adjustable Hi/Lo LED brightness switch allows you to take measures in low-light or direct sunshine, and the CAT IV 600 Volt safety certification and fully-insulated, wide-jaw alligator clips make it suitable for industrial applications. The PRT200 comes with a one-year guarantee and three built-in 30 in. The test leads include huge color-coded alligator clips, 4 AA batteries, and a bag case.
The Extech 480403 Motor Rotation and 3-Phase Tester is rated from 40 to 600 volts and can test the phase orientation of 3-phase power sources across a frequency range of 2 Hz to 400 Hz. LEDs show phase orientation (clockwise or counterclockwise) and whether each phase is active. In addition, it indicates the motor's rotation direction to ensure that it is not destroyed by faulty wiring. The meter comes with a cable, three huge color-coded alligator clips, a bag case, and a 9V battery.
The 480400 Phase Sequence Tester has a rated voltage range of 40 to 600 volts and can test the phase orientation of 3-phase power sources at frequencies ranging from 15 to 400 Hz. The multiline graphical LCD displays phase orientation (clockwise or counter-clockwise) and whether each phase is active. No battery is required. Includes cable, three huge color-coded alligator clips, and a bag case.
