The GSR-200 is an inexpensive GSR measurement device for classroom or laboratory use. It draws its power from any iWorx data acquisition device or standard transducer amplifier.

The GSR-200 functions by passing a small constant voltage across the skin and then measuring changes in resistance that may occur. The GSR-200 is shipped with a set of finger electrodes and a lab manual for galvanic skin response experiments.
