- "Please squeeze this."
The strength gauge was a small spherical device used by the Tok'ra when they wished to examine the strength of an individual.
The ball shaped machine was given to a person who simply needed to squeeze it with all their strength. The ball would then emit a high pitched noise which got louder the more pressure was put on it, sending information wirelessly to an accompanying data pad which provides the details on the strength used on it. The scientist can be a short distance away from the test subject.
The first time he was tested, Anise noted his strength was five times the strength of a normal Human; later, it was sufficient enough to break under the strain of the Human's enhanced strength. (SG1: "Upgrades")
