Use the PowerWatch as your first line of defense against power quality problems. Simply plug it into any power receptacle (120-volt North American or 220/240-volt Australian, European or UK) and begin monitoring and recording essential voltage disturbance information-surges, sags, outages, impulses, dropouts, and frequency variations. Set up your pre-determined disturbance threshold values or use the industry standard default values using PowerWatch software. No wiring or dangerous connections are required.
