basic hall effect apparatus
A basic apparatus for providing contact, power supply and support to a germanium crystal on a circuit board, in experiments on the Hall Effect or on conductivity.
The Basic Hall Effect Apparatus includes an integrated, adjustable constant current source to provide the current through the sample. The Apparatus also consists of a measuring amplifier, with offset compensation for Hall voltages and heating to raise the crystal to as high as 170°C. Furthermore, this product features temperature regulation and a switchable display showing Hall voltage, sample current, sample voltage or temperature.
Hall voltage and sample voltage can be tapped directly from the front panel. In addition, three equivalent voltage outputs for Hall voltage, sample current and sample temperature can be measured from the side.
The Basic Hall Effect Apparatus includes an attachment for assembling the apparatus on the U-shaped core of a transformer assembly kit, as well as two connecting leads with 8-pin miniDIN plugs.
