M91 FastHall™ Measurement Controller

A new approach to Hall measurement


The MeasureReady M91 is a revolutionary, all‑in-one Hall analysis instrument that delivers significantly higher levels of precision, speed, and convenience to researchers involved in the study of electronic materials.

Featuring Lake Shore’s patented* new FastHall measurement technique, the M91 fundamentally changes the way the Hall effect is 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.
