What is a Gauss Meter?
A Gauss is a common unit of measurement of magnetic field strength. The Gauss meter is a tool for measuring Gauss values. Inside a Gauss meter is a coil of thin wire. As a magnetic field radiates through the coil, it induces a current, which is amplified by the circuitry inside the Gauss meter. These meters vary in the strength of magnetic fields they are able to measure. A meter used for measuring EMFs from power lines, transformers, substations and appliances should be able to measure as low as .1 mg. Gauss meters vary in price and accuracy. They have either a single axis coil or a triple axis coil, with the single axis being much simpler and therefore much less expensive. To use the single axis meter, you point its one sensor in three directions, the X, Y and Z axes, and combine the readings in an equation to calculate the combined field strength. The triple axis meters are more complicated in their operations, but produce more accurate results. Another consideration is whether the
