Featuring Lake Shore’s patented* new FastHall measurement technique, the M91 fundamentally changes the way the Hall effect is generated and measured by eliminating the need to switch the polarity of the applied magnetic field during the measurement. This breakthrough results in faster and more accurate measurements, especially when using high field superconducting magnets or when measuring very low mobility materials.



  • Hall analysis including calculation of derived parameters for van der Pauw and Hall bar samples
  • FastHall technology eliminates the need for magnetic field reversal when measuring van der Pauw samples
  • Traditional DC field Hall measurement (field reversal required)
  • AC field Hall measurement
  • Manual step-by-step operation for full parameter control
  • Automatic optimisation of excitation values and measurement range
  • Extends mobility range down to 0.001cm2/V s, without using AC field techniques
  • High resistance option enables measurement of samples >10MΩ, up to 200GΩ
  • Derived parameter calculations with propagated errors
  • Operation over simple SCPI command interface or in conjunction with MeasureLINK-MCS software
  • Digital and analog I/O for simplifying integration and data gating
  • 3-year standard warranty
