A New Approach to Hall Measurement: MeasureReady M91

Lake Shore Cryotronics’ MeasureReady M91 is a highly innovative, all-in-one Hall analysis instrument that is capable of offering considerably higher levels of speed, precision, and convenience to scientists involved in the analysis of electronic materials.

The M91 features the new, patented FastHall™ measurement method from Lake Shore. By principle, the controller alters the way the Hall effect is measured by removing the need to change the polarity of the applied magnetic field during the measurement.

This process results in quicker and more accurate measurements, particularly when measuring very low mobility materials or when using high field superconducting magnets.

Simpler and More Convenient

  • Automatically performs measurement steps
  • Automatically selects ideal excitation and measurement levels
  • Offers detailed Hall analysis in an all-in-one instrument

  • Features a user-friendly interface

  • Easily integrates into existing lab systems

Makes Better Measurements, Faster

  • Enhances accuracy by reducing thermal drift
  • Eliminates the need to reverse the magnetic field
  • Performs up to 100× faster for low mobility materials


  • Can be used with all types of magnets
  • A new Hall system can be built, or a current one can be upgraded
  • Incorporates advanced Hall measurement capability to any lab

A Convenient, Single Instrument

Traditional Hall effect measurement systems (HMS) offer standard electrical measurement instrumentation integrated with a switching unit to measure Hall voltages and sample resistivity. However, they must rely on independent PC-based software to carry out pre- and post-measurement calculations, so as to eventually derive the physical parameters that scientists need to know — mobility, carrier type, resistivity, carrier concentration, and Hall coefficient.

The M91 FastHall™ measurement controller brings together all of the essential HMS functions into a single instrument, thus automating and enhancing the measurement process, and directly reporting the parameters that are calculated.
