The Jem'Hadar tricorder was a tricorder used by the Dominion.

In 2372, Temo'Zuma and Arak'Taral used tricorders to search for Miles O'Brien on Bopak III after he escaped from them. (DS9: "Hippocratic Oath")

The following year, the Jem'Hadar who accompanied Weyoun to Deep Space 9 detected the polaric particles from Elias Giger's cellular regeneration and entertainment chamber with their tricorders. (DS9: "In the Cards")
