Description
Measuring the salinity of seawater with the standard refractometer (the one normally sold) calibrated for saline solution (NaCl) (brine solution) will result in a deviation of up to 1.5 ppt. The AQPET Seawater Refractometer includes an automatic temperature compensation ATC device to avoid compensation errors.
It has been calibrated at 25°C, which is the suitable temperature for reef aquariums.
With the new version, thanks to the LED supplied , you can easily read the measured value in any external light situation.
