All swing-arm plastic hydrometers for aquarium use are only accurate when used within the normal range of operating temperatures for marine aquariums (77ÂºF.). 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.
Hydrometer is 3.5" wide x 0.5" thick x 5" high.
