Precision, 100pT Resolution Magnetometer

Fluxgate World: The A6320 precision, three-channel magnetometer accepts different fluxgate sensing heads and each channel can operate in direct or differential mode. Currently available heads include a single fluxgate for direct measurement of magnetic field strength and a twin, 2m separation head for differential measurement.

Direct mode operation allows field measurement for a broad range of scientific and engineering applications such as checking for flux leakage, stray flux and residual fields. The differential mode allows background fields to be cancelled out and the gain increased to detect very small anomalies in the field. This is of particular use in geophysical surveying and as a method of detecting the presence of objects that disrupt the background magnetic field.

Sensor heads are available to measure fields up to 16mT. Custom software is included for the display of readings on a standard PC or laptop. The instrument is powered by either 12V battery or 230V mains.
