Morphology
Both parts are literal technical nouns and the compound meaning is directly derivable: a declinometer (device that measures magnetic declination) associated with or mounted on a transit (a surveying instrument). Although the term is domain-specific, its meaning follows regular noun–noun composition and would be understandable to a learner who knows the constituent words.
Etymology
Transit declinometer comes from two parts: a small telescope used for measuring land called a transit and a tool called a declinometer that shows how much a compass needle 'leans' from true north. So the image of a turning telescope reading the needle explains why the name means an instrument used to 'measure magnetic declination'.
