FEREX 4.034
Digital fluxgate magnetometer for detection of ferromagnetic metals with data logging and comprehensive application software
Precise detection of geomagnetic anomalies. With the FEREX 4.034 detection of geomagnetic anomalies is as simple and precise as ever. The significantly improved signal-to-noise ratio, comprehensive application software and reduced weight facilitate detection. Up to 4 probes can be used on a probe holder. Linking a GPS system the exploration area and the tracks can be easily defined. The optional navigation system provides valuable information on the current position, deviation from the ideal track as well as the data quality already during data acquisition. Results are displayed directly on the color screen, providing initial analysis.
