Analisys Refractometer Electronic Meter
The AQPET Refractometer has been calibrated for the ionic composition of seawater. Measuring the salinity of sea water with the standard refractometer that normally sold calibrated for the saline solution NaCl brine solution will result in a deviation of up to 1.5 ppt. The AQPET Seawater Refractometer includes an ATC automatic temperature compensation device to avoid compensation errors. It has been calibrated at 25C, which is the right temperature for reef aquariums.uari reef.
