Instec, Inc. and Lake Shore Crytronics, Inc. have teamed up to provide the most versatile, precise, and affordable thermal and electrical measurement systems around.
The M81 Source Measurement Unit is a powerful simultaneous source module that is compatible with any Instec thermal probing stage or chuck. With between 1 to 3 source modules and 1 to 3 measurement modules, the M81 is ideal for Van der Pauw, four-point probing, Hall Bar, and more.
The M81 replaces multi-system setups by combining DC and AC sourcing along with DC and AC measurement and including a lock-in's level of sensitivity peformance.

Touchscreen Features
The M81's touchscreen front display allows for simple independent setup of each module’s output and input parameters. Range, amplitudes, frequencies, and filters as well as a variety of measurement settings are easily adjustable during experiments. Collecting multiple measurements as a source is ramped or parameters like temperature or magnetic field are changed is simple using the InstecApp which has been integrated with Lake Shore's native MeasureLINK software.
