saltwater Hydrometer & Digital Thermometer aquarium NEW
Brand: Aquarium Supplies
Model: R10 溫度指針比重計
Description: 1. Easy to use. 2. Green indicators are ideal range of water temperature and specific gravity for most salt water / marine aquariums. 3. Hydrometer measures specific gravity. 4. Need it for raising brine shrimp. CONTINUOUS USE:1.Submerge the hydrometer approximately 15cm(5.9 in) below the water's surface.2.Recommended specific gravity should read 1.020-1.023 for most marine aquariums.You must add marinemix when below this level, or add fresh water if above this level.
All swing-arm plastic hydrometers for aquarium use are only accurate when used within the normal range of operating temperatures for marine aquariums (77ºF.). This hydrometer is suppled with a digital thermometer to ensure that the water being tested is at the correct temperature. In addition to being used as a regular hydrometer for periodic specific gravity measurements, the unique, patented design enables this hydrometer to be installed permanently inside the aquarium or sump giving a continuous real-time reading of specific gravity.The water flow path resulting from this design minimizes bubble formation, increasing the accuracy of measurements.Comes with a suction cup for hanging inside aquarium.Size:Hydrometer is 3 1/2 in. wide x 1/2 in. thick x 5 in. high.
