[Product description]]

1. Insert hydrometer to the water tank or fish pond below 15cm until the water overflows baffle.

2. When the water reaches full state, take out hydrometer and place it on a horizontal surface.

3. The attachment of bubbles to the needle will cause inaccurate reading. Please Pat hydrometer carefully to shock the attached bubbles.

4. Read the specific gravity according to the inner scale, and read the salinity (PPT) according to the outer scale. It is recommended that the specific gravity of seafood pool seawater be1.020-1.023 between, that is, within the range of the security line.

5, square type: Specific gravity range: 1.000-1.030 salinity range: 0-40

 Long type: specific gravity range: 1.010-1.030 salinity range: 16-40

6. Rinse with clean water after each use.

* Hydrometer of the sea water that can float on the water surface;

* The specific gravity, salinity and conductivity of seawater are displayed at one time;

* Easy to use and easy to read;
