Tok'ra strength gauge
Device of Tok'ra design which measures the strength of a subject's grip. As pressure is applied, a high-pitched sound escalates until the individual applies maximum strength. The information is transferred via wireless to an accompanying Tok'ra data pad.
Strength gauges are metallic gray and can fit in the palm of a humanoid hand.
Upgrades - The Tok'ra Anise uses a strength gauge to measure the escalating strength of O'Neill, to the point where he eventually breaks the device.
