Product Details

There are several common methods used to measure specific gravity. The most common are (1) hydrometers, (2) conductivity meters and (3) refractometers.

Hydrometers are the most common instrument used in the aquarium industry.

  • Material: Glass Colour: As the picture
  • For Salt Water or Fresh water 
  • Easy to use
  • Measures both temperature and gravity of the water
  • Green indicators are ideal range of water temperature and specific gravity for most salt water / marine aquariums Instruction: Place the hydrometer into water, and let it flow freely in the water If water level below the green indicator means more fresh water is required If water level above the green indicator means more salt water is required Size:20cm/7.87"

 

Product Features

Normal Values & Definitions

  • When measuring how “salty” sea water is, we measure the “specific gravity”.
  • Salinity, a term that is often used when meaning specific gravity, is really a measurement of the sodium chloride component of sea water. Specific gravity is the ratio between the weight of a given volume of sea water and the weight of an equal volume of distilled water. It is usually measured with the aid of an hydrometer.
  • The value of the normal specific gravity of sea water at a temperature of 20°C is 1.024. SALINITY is a measure of the total salts in a given weight of sea water. It is measured in parts per thousand, Normal value is 34%. Do not confuse salinity with specific gravity.
