the MFJ-850B

The MFJ-850 Line Voltage Meter helps you see low voltage "Brown out" conditions and surges that can damage your expensive electrical equipment by letting you see line voltage dips.

The MFJ-850 shows line voltage with a color coded scale that reads voltage from 95 - 135 volts with 2% accuracy. It measures a compact 2.25x2.25x1.5 inches and simply plugs into an AC outlet. Click here for an alternate view.
