AccuraSea Seawater Calibration Solution 250 ml – Natural Seawater-Based Reference for Marine Aquarium Instruments
AccuraSea Calibration Solution is the only calibration fluid made from real natural seawater, micron-filtered and UV-sterilized, then adjusted with reverse osmosis water to match S = 35 salinity or conductivity of 53 mS/cm at 25°C (77°F).
It provides unmatched accuracy for calibrating refractometers, verifying swing-arm hydrometers, and even acting as a reference solution for checking the accuracy of test kits. Unlike artificial calibration fluids, it contains the full spectrum of natural dissolved salts, making it ideal for precise marine aquarium management.
