Easy-read swing-arm hydrometer measures specific gravity and salinityUnique design takes true water samples for accurate readingTemperature-corrected and accurate to ?0.001 specific gravity unitsPrecision hydrometer tests both salinity and specific gravity accurately and without getting your hands wet. Distinct vertical design takes water samples six inches below the surface where samples are more accurate than water at the surface. Gently diverts water to reduce excess bubbles and convenient self-leveling hanging device further eliminates inaccurate results. Wide range hydrometer reads temperature-corrected readings accurate to ?0.001 specific gravity units. Certified calibration for precise and reliable results. Durable plastic construction for years of use. Measures 16 - 43 PPT salinity and 1.012 - 1.032 specific gravity. 6-1/4" x 11" high.Please click on "More Information" for directions and ideal saltwater aquarium parameters.
