Tropic Marin Hydrometer (Best Choice)
Hydrometer ]For marine aquariums.These high precision hydrometers are handmade in Germany by experienced craftsmen.
They have a maximum deviation of 0.0005.These hydrometers never need calibration. Indispensable for scientists and the committed hobbyist. The higher price will soon pay off by an always exact salinity in the aquarium.Scale from 1.018 to 1.028, with a marked recommendation range 1.021 to 1.024.

For sale R400 been used 3times, still brand new one month old
