QIANJINL Salinity Meter Aquarium Hydrometers Salinity Tester Hydrometer Saltwater Aquarium Pool Fish Tank Water Tester Sea Water Salinity Specific Gravity Test(Rectangle)

• ▶Material: The salinity tester is made of plastic, transparent, robust and durable structure.
• ▶Simple to use:Keep your hands clean, insert the hydrometer into the water tank or fish pond 15 cm (6 inches) below, avoid air bubbles adhering to the hydrometer during the test.
• ▶Precision:Accuracy can reach + (-) 0.002 specific gravity units, the highest accuracy is when the water temperature is 18-28 degrees.
• ▶Safety zone indication: read the specific gravity according to the inner scale, and read the salinity (PPT) according to the outer scale. The safe and healthy proportion of seawater is between 1.020-1.023(ppt value: 27-31 degrees).
• ▶Wide Usage:The aquarium hydrometers suitable for measuring salinity in aquariums, fish tank, ponds, pool,etc,can be used for the salinity test of fresh water and sea water.
