Hydrometer With Temperature Indicator

Manufacturer Part Number: 12010All 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 3.5" wide x 0.5" thick x 5" high.
