DX-100 Hall Effect Measurement Equipment
DX-100 Hall Effect Measurement Equipment 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, so the hall measurement equipment is a necessary tool for understanding and studying the electrical properties of semiconductor devices and semiconductor materials.
DX-320 System SourceMeter
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.
