Succeeding the TR-580 Tricorder VII, the TR-590 Mark X Tricorder featured nearly identical control interfaces. The entire unit, however, was streamlined and made much smaller, featuring a more angular design. (DS9: "The Way of the Warrior"; VOY: "Initiations")

Functioning very much like the previous model of Starfleet tricorder, the Mark Xs were stored in most equipment lockers on board Federation starships. (VOY: "Relativity")

Discovered by the Maquis, the Mark X tricorder could be prevented from attaining credible readings when subjected to concentrated thoron particles. (VOY: "Basics, Part I")

The Mark X Tricorder was reportedly heavy for its size as indicated by Lt. Torres when she received a small gift from Tuvok during a holodeck generated baby shower. Torres asked if it was her child's first tricorder as the gift was small yet heavy. (VOY: "Human Error")

Introduced along with the Mark X standard tricorder, a medical tricorder variant was in use aboard Federation starships as early as 2373.

Generally identical to the standard tricorder, the medical featured a detachable hand scanner (as in previous models) that fit into the back of the unit. It was distinguished by blue ID indicator lights and a blue-glowing sensor surface. (Star Trek: First Contact; VOY: "Favorite Son"; DS9: "Soldiers of the Empire")

The medical tricorder had duritanium casing, and measured 7.6cm x 9.8cm x 3.2cm, and featured an alphanumeric display. (VOY: "Retrospect")
