Hall Measurement Controller: MeasureReady M91

The MeasureReady M91 FastHall™ measurement controller from Lake Shore Cryotronics is a groundbreaking, multi-purpose Hall analysis instrument. The controller offers considerably higher levels of speed, convenience, and precision to researchers who perform analysis of electronic materials.

The M91 features Lake Shore’s new, patented FastHall™ measurement technology, thus essentially transforming the Hall effect measurement technique by avoiding the need to change the applied magnetic field’s polarity while performing the measurement.

This advancement leads to more accurate and more rapid measurements, specifically when high field superconducting magnets are used or when materials of very low mobility are measured.

Simpler and More Convenient

  • Offers comprehensive Hall analysis
  • Performs multiple functions
  • Automatically performs all measurement steps
  • Features a user-friendly interface
  • Easily integrates into existing lab systems
  • Automatically chooses the ideal excitation and measurement levels

Makes Better Measurements, Faster

  • Measures up to 100x faster for materials of low mobility
  • FastHall™ avoids the need to reverse the magnetic field
  • Enhances accuracy by reducing thermal drift


  • Cutting-edge Hall measurement capability can be added to any lab
  • Option to develop a completely new Hall system or upgrade an already existing system
  • Possibility to be used with any magnet type

A Convenient, Single Instrument

A conventional Hall effect measurement system (HMS) offers fundamental electrical measurement instrumentation integrated with a switching unit for the measurement of Hall voltages and sample resistivity.

However, a HMS relies on separate PC-based software to carry out pre- and post-measurement calculations to eventually obtain the physical parameters that must be known by researchers — Hall coefficient, carrier type, mobility, resistivity, and carrier concentration.

The M91 FastHall™ measurement controller integrates all the essential HMS functions into a single instrument, thereby optimizing and automating the measurement process, and enabling direct reporting of the calculated parameters.
