Hydrometer: Introduction. Hydrometers measure the relative density of liquids by incorporating the concept of buoyancy. These hydrometers are typically graduated and calibrated with single or multiple scales, such as specific gravity and API gravity/5(33). Marineland Labs/Aquarium Systems Hydrometers, part 1. By Steven Pro. I am going to take a slight departure from my regular Impressions column this month. Instead of merely describing what I think about a particular type of equipment and the brands/models available, I will instead be detailing some product testing that I conducted.
