Two Little Fishies AccuaSea - Pisces Pet Emporium

AccuraSea® Seawater Reference/Calibration Solution is the only calibration solution of its kind made from real seawater. It’s pure natural seawater micron filtered and UV sterilized then adjusted with reverse osmosis water to match the standard S 35 or 53 ms/cm at 25°C (77°F).

Use it to accurately calibrate seawater refractometers and to 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.

Direction for Use For Refractometer Calibration

Use a soft clean cloth and pure freshwater to wipe clean and then dry the prism slide surfaces. Put a few drops of AccuraSea SRCS on the prism slide and follow manufacturer instructions for taking a reading and setting the calibration. Calibrate to 35 ppt. Clean and then dry the prism slide surfaces. Now place a few drops of the water to be tested on the prism slide and read the density of the water sample. Clean and dry the prism slide surfaces again before storing the refractometer.
