Electrical Measurement Solution – Power Quality
120V, 220/240V, 50/60 Hz Voltage Disturbance Recorders
PowerWatch is the easiest way to monitor and record essential voltage disturbance information from any 120 volt North American or 220/240 volt Australian, European or UK power receptacle. Just setup your pre-determined disturbance threshold values or use the industry standard default values and plug it in. No wiring or dangerous connections required.
