QIANJINL Aquarium Hydrometers Salinity Meter Saltwater Tester Sea Hydrometer Rectangle

Description

1)Product Detail specification: Rectangle(L:2.95in x H:7.4in x THK:0.59in ,W:0.23lb) Square(L:3.54in x H:4.72in x THK:0.59in, W:0.21lb) Package Content: 1 Pack 2)Salinity Meter Instructions (1)Insert the hydrometer below 15 cm (6 inches) of the water surface of the water tank until the water overflows the baffle. During the test, let the hydrometer slowly fill with water to prevent air bubbles from adhering to the pointer. (2)When the water is full and level with the top of the baffle, take out the hydrometer and place it on a level surface. (3)Air bubbles attached to the pointer will cause inaccurate readings, tap the hydrometer carefully to shake out the attached bubbles. (4)Read the specific gravity according to the inner scale, and read the salinity (ppt) according to the outer scale. It is more suitable for the specific gravity to be between 1.020-1.023. (5)Rinse with clean water after each use. 3)NoteBefore using the hydrometer for the first time, fill it with warm water and detergent to clean the internal surface oil stains, which can make the accuracy higher.Please rinse with clean water after use. If the salt crystallizes in the hydrometer, soak the hydrometer in warm water or vinegar for 30 minutes, then rinse with water and air dry.

?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. ?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). ?Precision:Accuracy can reach + (-) 0.002 specific gravity units, the highest accuracy is when the water temperature is 18-28 degrees. ?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. ?Material: The salinity tester is made of plastic, transparent, robust and durable structure.
