Lakeshore M91 FastHall™ measurement controller very good price

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 precise measurements, especially when using high-field superconducting magnets or when measuring very low-mobility materials.

You can also harness the power of FastHall along with a Quantum Design PPMS — check out our M91 FastHall™ analysis kit for PPMS®

A convenient, single instrument

Traditional Hall effect measurement systems (HMS) provide basic electrical measurement instrumentation combined with a switching unit to measure sample resistivity and Hall voltages but must rely on separate PC-based software to perform pre- and post-measurement calculations in order to ultimately derive the physical parameters that researchers need to know—resistivity, carrier type, carrier concentration, mobility, and Hall coefficient.

The M91 FastHall measurement controller combines all the necessary HMS functions into a single instrument, automating and optimizing the measurement process and directly reporting the calculated parameters.
