Specific Gravity Meters & Hydrometers : For measuring your marine water salt content
Instant Ocean Hydrometer
Aquarium Systems Instant Ocean SeaTest TK-505 Hydrometer
Instant Ocean Hydrometer's design delivers precise full-range salinity (PPT) and specific gravity readings (SG) - accurate to 0.001 - every time.
Easy-fill convenience keeps hands dry when filling.
It has a durable, permanent needle mount and easy-read 2-color scale with "safe zone"
Ideal for use in water temperatures of 68 - 85 degrees F.
Just scoop in the water to be tested, and read off the scale once the floating needle has settled.

Tetratec Comfort Hydrometer
Tetratec Comfort Hydrometer : Measures Salinity & Specific Gravity
Extremely accurate and easy to use swing needle hydrometer.
Provides temperature corrected readings in water that is in the temperature range of 20-29 deg C
Ensure there are no air bubbles attached to the swing arm needle before taking the reading, and wash out with fresh clean water after use

Marine fish and corals require stable water conditions, which makes regular checking of salinity important. It’s also necessary to check salinity when making up new water for water changes.
The TetraTec Hydrometer makes it simple to accurately check the salt content of water, giving precise readings over a wide temperature range (20 – 29°C). It works by measuring the specific gravity (relative density) of the water, and converting this to salinity.
All you need to do is fill up the hydrometer with water, and read the value off the scale printed on the side.

Waterlife SeaDrometer
For the measurement of seawater salinity
The measure of salinity (saltiness) levels in water is Specific Gravity (S.G.).
The SeaDrometer is a scientific instrument used to measure the correct salinity level for the type of marine creatures in your set-up.
The fishes' indigenous region dictates the level of salinity they will tolerate. e.g.

Indo Pacific = 1.018 to 1.022
Caribbean = 1.020 to 1.025
Red Sea = 1.028 to 1.034
If the S.G. reading is too low, add Waterlife Ultramarine sea-salt to increase the S.G.
If the S.G. is too high for the species being kept, add fresh-water.
N.B. Always effect changes to S.G. of your system gradually so as not to cause shock to your fishes.
Uses:
