Graham Stetzer Microsurge Meter
A Meter to Measure Dirty Electricity

The GS Microsurge meter was specifically designed as a companion to the GS filters. The meter measures the level of harmful electromagnetic energy present. Its primary use is as a guide to effectively install GS filters.
The Microsurge meter will help you to test for dirty electricity and later allow you to monitor the effectiveness of your filter arrangement.

Microsurge meters are low cost and easy to use by non-technical people. The GS units are effectively a measure of harmful high frequenicy electromagnetic energy or ‘dirty electricity’. These higher frequeicies are considered most detrimental to human health.

The meter measures the amount of radio frequency energy (above 4 kHz to 100 kHz) present on a building’s electrical circuits and displays it in a digital format. A meter reading of 50GS units or lower is good, 25 or below is optimal. Adding more GS filters will remove the dirty electricity from the electrical circuit and therefore lower the readings you see on the meter.

Recent research has uncovered an alarming increase in cancer rates amongst groups of people who are exposed to high frequency voltage transients and EMF pollution. Types of cancers observed have included, but are not limited to, melanoma, breast, uterus, and thyroid cancer, as well as childhood and adult leukemia. The relatively short latency time of melanoma and thyroid cancers suggest that these cancers might be more sensitive to the effects of high voltage transients than other manifestations of this disease.
