The hall measurement system consists of an electromagnet, electromagnet power supply, high precision constant current source, high precision voltmeter, Hall effect sample holder, standard sample and system software.

 

The Hall effect system is used to measure important parameters such as carrier concentration, mobility, resistivity,  Hall coefficient and other important parameters. These parameters are necessary to understand the electrical properties of semiconductor materials.

The DX-320 effect meter specially developed for this instrument system assembles a constant current source and a switch (a six-and-a-half microvoltmeter and a Hall-complex switching relay) into one. Greatly reduced the connection and operation of the experiment. The DX-320 can be used alone as a constant stream and a microvolt.
