Strength gauge

The Tok'ra Biosensor is a device used by the Tok'ra when examining a person.

These small machines are placed on the skin of a patient and transmit physiological data into an informational terminal even if its quite a distance away. Such machines were used by Anise to examine SG-1 when they volunteered to use the Antoniek armbands. (SG-1 episode: Upgrades)
