Salinity is a measure of the concentration of dissolved salts in the water. Natural Seawater is generally in the range of 1.021 to 1.025. Salinity is very important to keep steady and should be measured with a refractometer or hydrometer.
PINPOINT Salinity Monitor™ will accurately and immediately measure the amount of salt in any marine or freshwater system.
The unique design of the Coralife Deep Six Hydrometer allows hobbyists to take water samples at six inches in depth without submerging their hands in the water, thus avoiding the possibility of contamination.
The Ammonite shaped hydrometer from AquaticLife™ integrates a scale for accurate measurement of salinity in a reef or marine aquarium.
Simply the best way to check salt concentrations in aquariums and ponds! Our hand held salinity refractometer is not only temperature compensated but allows for low level readings and fine resolution. It yields precise low level readings to ensure proper salt content.
