Salinity fluctuations stress your fish and corals. By relying on those notoriously inaccurate swing arm hydrometers you may be harming your cherished specimens!
Stop guessing at your salinity and make a vital investment in your aquarium’s health. Our precise and accurate refractometer allows you to determine exactly what your salinity is with just a couple drops of water and a few seconds. It’s simple to use, extremely accurate, and is constructed to exacting standards so that it will perform flawlessly for years. The Automatic Temperature Compensation (ATC) design allows the instrument to read accurately no matter what your room temperature is – just put a few drops of water on the prism, swing the cover down, wait a few seconds to allow the water to adjust to the same temperature as your refractometer, and then look through the adjustable eyepiece to read the exact salinity of the sample. It couldn’t be any easier!
Your new refractometer will arrive calibrated and ready to use in a durable plastic carrying case with a pipette, convenient microfiber lens cloth, instruction sheet, and calibration screwdriver.
