D. Manometer gauge
Answer:D
Which type of pressure gauge is best suited for measuring vacuum pressures?
A. Bourdon tube gauge B. Diaphragm gauge C. Bellows gauge D. Manometer gauge
Explanation: Manometer gauges are best suited for measuring vacuum pressures, as they use a U-shaped tube filled with liquid to indicate the pressure difference between the vacuum and atmospheric pressure.
