LAKESHORE 420 GAUSSMETER LCD GAUSS TESLA ~ 3 mG (0.3 µT) to 300 kG (30 T)

The Model 420 has an easy-to-use front panel that includes an alphanumeric Liquid Crystal Display (LCD) for message-based front panel operation. Perform and monitor most operations through the front panel keypad and message display. The display has a resolution of 4-characters.

The Model 420 measures fields from 3 mG (0.3 µT) to 300 kG (30 T), in either gauss or tesla. Set field ranges either manually or with auto ranging. The Range key displays the full scale value and cycles through allowable ranges for the probe installed. The Auto Range function automatically selects the range with the best resolution for the measured field.

The gaussmeter measures both DC and AC field values. In DC operation, it displays the field at the probe with the sign (orientation), followed by appropriate field units. In AC operation, it displays a RMS value for the field at the probe. The DC and AC values are available over the Serial I/O Computer Interfaces and also the Corrected Analog Output. The Monitor Analog Output displays actual magnetic field waveform.
