The Pinpoint Salinity Monitor will accurately and immediately measure the amount of salt in any marine or freshwater system. The reading is fully temperature compensated, which is difficult or impossible with nearly any commercial hydrometer. The conversion chart will precisely show the corresponding density (specific gravity) or % salt (refractometer) values.
Given proper care, the Pinpoint Salinity Monitor should last a lifetime.
Powered by a standard 9-volt battery (not included).
Optional AC Adapter Kit (Sold Separately).
