The SDL900 is an AC/DC Magnetic Meter and Datalogger with automatic temperature compensation. The SDL900 utilizes Hall effect sensor. This meter features an adjustable data sampling rate from 1 to 3600 seconds. Complete with uniaxial magnetic probe sensor with protective cover, SD memory card, 6 AA batteries and hard carrying case.

Extech’s SDL900 measures and datalogs both AC and DC Magnetic Field in Gauss and mT (milli Tesla) with a uniaxial Hall effect sensor and built-in ATC. Internal memory stores up to 99 readings, while SD memory card (included) allows continuous datalogging and readings can easily be exported to an Excel® format for further analysis.
