AFAIK never used in canon.

Klingon tricorders were seen and used by Kruge's landing party in ST3.

The name tricorder refers to "a triple sensor-recorder-analyzer function" (ghunchu'wI').

PUN:
The GTE Expedition Trike is a well-known brand of adult racing tricycle made by Greenspeed USA.

Are these truly "well-known", and did they even exist at the time of TKD's publication? And does Okrand own one?

{Hoq} "expedition" (= "trek) + {ra'} "order" > "trek-order" > "tricorder" is another possible derivation.
