Directly reads the absolute salinity of water at 25°C / 77°F.
Specifically designed for the ionic content of seawater (NSW) for more accurate salinity measurements.
Calibrated for seawater (NSW) at 25°C / 77°F.
Easier to read, higher resolution display, focused on the relevant range for reef aquariums up to 40ppt.
Includes Built-in Automatic Temperature Compensation (ATC) for accurate measurements at normal ambient temperatures.
