ZRM&E Seawater Hydrometer for Aquarium Aquaculture Seawater Densimeter Ocean Hydrometer Salinity Meter for Fish Tank…

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

Made of high quality plastic, aquarium transparent, automatic accurate reading brine hydrometer
Accurate, durable and easy to read salt and specific gravity of your marine aquarium, small and waterproof. If the specific gravity is between 1.000-1.019, it indicates that the specific gravity is low; if the specific gravity is between 1.020-1.023, it indicates that the specific gravity is normal; if the specific gravity is between 1.024-1.030, it indicates that the specific gravity is high
The external range of the scale indicates salinity (PPT), and the internal range of the scale indicates gravity. And clearly mark the safe area. Application range: 0-40 degrees (1.000-1.030). If the salinity PPT is between 32-40, it indicates that the salinity is high; if the salinity PPT is between 27-31, it indicates that the salinity is normal; if the salinity PPT is between 0-26, it indicates that the salinity hydrometer is low
Wide range of applications: Suitable for salt water and sea water fish tanks. Perfect for testing salinity and specific gravity of saltwater and seawater tanks, including solubility and specific gravity scales. Suitable for fresh water and sea water
Easy to read swing arm pointer and ultra wide stable base can provide accurate test results
