Current & Voltage Monitors

Big Bear Instruments offers a wide variety of current monitors and phase/voltage monitors.  The current monitors are used to do just that -monitor current in its necessary application.  Many units can detect over and/or under current too which is important for avoiding an issue with continuous operation of critical industrial machinery. The phase/voltage monitors are designed to protect applications from things like phase loss, under or over voltage, and machine failure.  Sort by manufacturer, series, monitor type, or part number.
