Easy-read swing-arm hydrometer measures specific gravity and salinity
Improved calibration ensures more accurate reading of aquarium water
Temperature-corrected and accurate to ±0.001 specific gravity units
Tests both salinity and specific gravity accurately
Distinct top fill 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 that can result in inaccurate, high readings.
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.
Temperature-corrected readings from 68° and 85°F. Measures 0 - 40 PPT salinity and 1.000 - 1.032 specific gravity. 3-3/4" x 5-3/4" high.
