ZRM&E Seawater Hydrometer for Aquarium Aquaculture Seawater Densimeter Ocean Hydrometer Salinity Meter for Fish Tank Salinity Specific Gravity Test

Specification: Type: Seawater Length: 19cm Width: 7. 5cm Thickness: 1. 5cm Weight: 104g Color: Transparent Material: Plastic Package includes: 1 x Seawater Insert the hydrometer 15cm below the water until the water overflows the baffle When the water is full, take out the hydrometer and place it on a horizontal surface Bubbles attached to the needle will cause inaccurate readings. Tap the hydrometer carefully to shake out the adhered bubbles Read the specific gravity according to the internal scale and the salinity (PPT) according to the external scale. It is suggested that the specific gravity of seawater in the seafood pool should be between 1. 020-1. 023, that is, within the safety line Specific gravity range: 1. 000-1. 030 salinity range: 0-40 Rinse with water after each use Sea water hydrometer floating on water surface Primary display of specific gravity, salinity and conductivity of seawater It is easy to use and read.
