🔍 Key Concepts
• Meteorological instruments used on board for weather observations
• Difference between pressure, temperature, humidity, and wind measurements
• Common instruments: barometer, thermometer, anemometer, and hygrometer
đź’ Think About
• Think about what aspect of the air is most associated with moisture and comfort levels for crew and cargo.
• Match each choice with the correct standard instrument name you already know (for example, what device normally measures pressure?).
• Consider how you would monitor conditions that can lead to fog, condensation, or sweat on bulk cargoes.
âś… Before You Answer
• Identify which choice relates to moisture content in the air rather than force, heat, or motion.
• Eliminate the options that you know belong to other well-known instruments (barometer, thermometer, anemometer).
• Ask yourself: which of these properties—pressure, humidity, temperature, or wind—directly affects dew, fog, and condensation?
