EMPAR Electronics was started by Physics Professor Michael Reshchikov to develop low-cost set-ups for electrical and optical characterization of semiconductors and to produce compact setups for Physics experiments in Colleges.
The idea to build a portable Hall Effect setup emerged after our unsuccessful attempts to find such a product on the market. Hall Effect setups used in advanced lab courses often require lab space or they work well only with expensive semiconductors (such as Ge samples). Often, instead of measuring the concentration of charge carriers and their mobility, the educational Hall Effect setups measure relatively weak magnetic fields with a simple Hall-Effect Sensor.
