Here we provide a variety of sensors for measurement of non-biopotential signals.  Sensors designed for use with a specific brand of biosignal acquisition system are listed in a brand-specific category.  Sensors that are general purpose and may be used with a variety of acquisition systems are listed in the Other section.  Note that we cannot guarantee compatibility of sensors with acquisition systems we do not sell or support.  When in doubt, please write or call to inquire rather than just ordering.  Used sensors cannot be resold so they are non-returnable.
