Many tank inhabitants are sensitive even to minor changes of the water conditions. For an exact, reliable measure of the specific gravity, Tropic Marin® offers a high-precision instrument. The hydrometer is handmade and designed to float vertically in the water. The maximum deviation is about 0.001 at 77° F (25° C).
Float freely in any vessel of adequate volume (e.g. the Tropic Marin® MEASURING CYLINDER). For most exact results the temperature should be at 77° F (25° C).
The recommended range is about 1.025 to 1.027 – readable at the blue printing zone.
Please note: The salt content of sea water is usually measured as specific gravity. Please check for the blue printing and the indication “Specific Gravity” at the Tropic Marin® High Precision Hydrometer.
Some countries measure the salt content as “density”. Therefore Tropic Marin® offers a high precision Areometer, which has a green printing and the indication “Dichte/Density” (see Difference between density and relative density).
