All-in-one Hall analysis instrument from Lake Shore Cryotronics delivers significantly higher levels of precision, speed, and convenience

This video looks at the MeasureReady™ M91 FastHall™ measurement controller, an all-in-one Hall analysis instrument from Lake Shore Cryotronics that delivers significantly higher levels of precision, speed, and convenience to researchers involved in the study of electronic materials.

The measurement controller combines all the necessary Hall measurement system functions into a single instrument, automating and optimizing the measurement process, and directly reporting the calculated parameters. With Lake Shore’s patented 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.

The M91 is extremely fast, reducing analysis time in some cases by 100 times. Most commonly measured materials can be analyzed in a few seconds. Even extremely high resistance (up to 200 GΩ) or low-mobility (~0.001 cm2/V s) samples can generally be analyzed in under two minutes.

Also available: the M91 controller provided as part of a fully integrated, high-precision tabletop system for simplified Hall measurements and less experimental setup.
