When it comes to measuring Salinity, refractometers are one of the most accurate tools available to reefkeepers. Thankfully, they are also relatively inexpensive and straightforward to use. What many hobbyists may not be aware of though is that not all refractometers are created equal, indeed, some are actually calibrated to measure a saltwater ‘brine’ solution rather than true seawater. Although still useable, this can mean that the reading obtained from such units can be slightly misleading to the unsuspecting hobbyist. To-date, refractometers calibrated for true seawater have been few and far between but a new option has recently become available from Red Sea.
