Features
Salinimeter: fish pool, both inside and outside the cylinder can be read. the hydrometer that can float on the surface of the water is simple and easy to read.
Specific gravity hydrometer: it is easy to read and the precision can be + (-) 0.001 units of specific gravity. professional design make it able to get accurate reading when the temperature of the fishpond is at -28 degrees.
Aquarium gravimeter: keeping your hands clean and can prevent pollution of water from the fish pond.
Salt water gravimeter: the proportion of water sample can be automatically detected. the proportion, and conductivity of sea water are shown once.
