The measurement device (3) comprises a metallic body (5) fixed in the wall of a reactor coolant pipe (1). The metallic body (5) is pierced in order to constitute a first channel (8) communicating with the inner volume of the pipe (1) by a plurality of coolant inlet openings (14) and a second channel (12) communicating with the inner volume of the pipe (1) by at least one coolant outlet opening (15) and enclosing the measurement probe (20) in a zone situated between the end of the second channel (12), which end is connected to the first channel (8), and the coolant outlet opening (15). The coolant inlet openings (14) are disposed on one frontal face of the metallic body (5) in the flow direction (6) of the coolant, and the outlet opening (15) is located on an opposite face thereof.
