Special Features
This measures and datalogs the AC and DC Magnetic Field in Gauss and mT (milli Tesla) with a uniaxial Hall effect sensor and built-in ATC. With a North / South pole indicator, clearly on display for easier readings. The RS-232 interface contains optional software for additional use.
Its internal memory stores up to 99 (manual) readings, whilst the included SD memory card allows for continuous datalogging and readings that are easily exportable to an Excel® format for further analysis.
