【 Product Description 】
1. Insert the hydrometer below 15 cm of the water tank or fish pond until the water overflows the baffle.
2, when the water has reached a full state, take out the hydrometer and place it on a level surface.
3, bubbles attached to the needle will lead to inaccurate reading, carefully tap the hydrometer to shake out the adhered bubbles.
4, read the specific gravity according to the inner scale, read the salinity according to the outer scale (PPT), it is recommended that the specific gravity of the sea water in the seafood pool is between 1.020-1.023, that is, within the line range.
5, square type: specific gravity range: 1.000-1.030 Salinity range: 0-40
6. Rinse with clean water after each use.
* Hydrometers that float on the surface of the water;
* Seawater specific gravity, salinity, conductivity display;
* Simple to use, easy to read;
* High transparency using acrylic.
