Tropic Marin 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.
