The Extech PRT200 is used to quickly check a three phase system's phase sequence and phase status.
With 75 to 1000V AC input voltage and 45 to 65Hz frequency range this tester is suitable for use with a wide range of phasing applications and uses LED indicators to show phase orientation and whether each phase is currently live or not.
If correct phase is detected a beeper will sound intermittently while a continuous beep will sound is phase is found to be reveresed. When testing life is made easier with the PRT200 as it includes an integral back magnet, allowing it to be mounted to a metallic panel for hands-free operation.
The tester is suitable for use both indoors and outdoors due to the ability to adjust the brightness of the LEDs to accomodate for high light or dimly lit areas. The alligator clips included with the tester are also fully insulated, ensuring user protection at all times.
