Measure the Density of Saltwater by A Digital Refractometer from FJDynamics
To measure the density of saltwater in fish and coral tanks, I used a simple plastic hydrometer and a digital hydrometer from another manufacturer. However, that simple hydrometer broke in just a few months, and the digital hydrometer from another company had problems, such as the power not turning on after being used a few times, and we worried about issues with durability.
Then I found FJDynamics` digital versatile meter (digital refractometer), and liked how it is accurate no matter how many times it is used, is easy to carry, and has a moderate weight with a high-class feel.
I measure density tens of thousands of times a year, so I will continue to use it regularly.
