Graham Stetzer Microsurge Meter
he STETZERiZER® Microsurge Meter by Graham-Stetzer is designed to separate the power line frequency to detect and respond to low level high frequency voltages caused by transients and harmonics on power lines. The level of these voltages is measured in GS (Graham-Stetzer) units and will vary with electrical equipment and loads. This device is recommended for use in conjunction with original STETZERiZER® filters. The STETZERiZER® Microsurge Meter was specifically designed as a companion to the STETZERiZER® Filters. The meter measures the level of harmful electromagnetic "energy" present, and its primary use is to guide effective STETZERiZER® Filter installation. Patents Pending. All Rights Reserved.
