    • STETZERiZER® Filter



      The STETZERiZER® Filter is based upon 100 year-old science and power engineering principles. Newly introduced is the design, which is focused on the needs of the customers in homes, offices, schools, etc. Filters have been extensively applied for decades by industrial users and the electric utility industry itself. The STETZERiZER® Filter is designed to filter harmonics and other high frequency current (trash) from the electrical environment, thereby reducing the potential for leakage into the human environment and creating additional trash in non-liner loads (televisions, computers, variable frequency drives, energy-efficient lighting, etc.).

    • STETZERiZER® Microsurge Meter



      The 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.
