Measure Hall voltage and conductivity in doped and undoped germanium, up to 140 °C.


The Hall effect unit is used for holding and supplying Hall effect carrier boards with doped and undoped germanium crystals. It enables temperature-dependent measurement of Hall voltage and conductivity.

| Weight | 0.6 kg |
All units adapted for 110V/60Hz. Contact us for volume pricing and grant assistance.
Move the magnetic field and switch between n-type and p-type germanium. The Hall voltage reverses sign for the other carrier type.
Bring this to your lab →Insert a doped (n-type or p-type) or undoped germanium carrier board into the unit.
Vary the magnetic field and sample current, up to ±55 mA, and record the Hall voltage that appears across the sample.
Warm the sample up to 140 °C to see how conductivity and carrier behavior change, and tell n-type from p-type by the sign of the voltage.
Typical student results: opposite Hall voltage signs for n-type and p-type germanium (illustrative).
Yes. Units supplied through American Scientific are adapted for 110V/60Hz and supported in the U.S., including warranty and replacement parts.
Tell us about your lab in the form above and we'll put together a complete, ready-to-teach configuration, so nothing is missing on day one.
Often, yes. Many institutions fund PHYWE equipment through NSF, Title IV and CTE programs, and our team can help you find and apply for the right opportunity.
