Do you know the difference between
a hygrometer and a hydrometer? A hygrometer
measures humidity, the amount of water
vapour in air. A hydrometer, on the other
hand, measures the density or specific
gravity (SG) of a liquid by floating in
the liquid.

OK, so it should be "hygrometer" in this case!

(Is "vapour" English English BTW?)

you're welcome.

Thank you!
