  Product Description Designed to accurately measure the absolute salinity  of seawater at 25 C/ 77 0 F by measuring the ionic content of seawater (most industry standard refractometers are calibrated for salt brine at 15 o C/59 o F and not as accurate). Calibrated specifically at 25 o C/77 o F, the normal temperature range for reef / marine aquariums  Easier to read, higher resolution display, focused to the relevant range for reef aquariums of up to 40ppt Includes Integrated Automatic Temperature Compensation (ATC) for accurate measurement at standard ambient temperature (slight temperature differences will not adversely affect the readings).
