Two Little Fishes AccuraSea. Seawater Reference and Calibration Solution, 250 ml.Do you think its important to maintain salinity precisely? Were with you. Thats why we created AccuraSea Seawater Reference and Calibration Solution, the only calibration solution of its kind made from real seawater. Its pure natural sea water micron filtered and UV sterilized then adjusted with reverse osmosis water to the standard S = 35 or conductivity of 53 mS/cm at 25C (77F). Use it to accurately calibrate seawater refractometers and check the accuracy of swing-arm hydrometers. You may also want to use it as a reference for test kits used to measure the concentrations of various seawater components, since it is natural seawater with the correct and well-known concentrations of all dissolved salts.
