Coralife Deep Six Saltwater/Reef Aquarium Hydrometer Improved Calibration ESU

Description

Deep Six Hydrometer from Coralife.
The re-designed deep six hydrometer with improved calibration and bubble diffuser ensures more accurate readings of your aquarium salt levels. Also includes a built in base so you can rest the hydrometer on a counter top or other flat surface when taking salt readings.
The Deep Six Hydrometer has a unique design that allows the hobbyist can take a water sample at six inches in depth without submerging their hands in the water, thus avoiding the possibility of contamination. Samples taken at six inches in depth have been proven to give a more accurate salinity reading than surface samples. Every unit is calibrated and tested for accuracy using advanced testing procedures. With its durable construction and easy-to-read scales, the Deep Six is guaranteed to provide years of reliable performance. Designed to give temperature-corrected readings in warm water aquariums, readings can be read in ppt and specific gravity. The Deep Six is accurate to plus or minus 0.001 specific gravity.
