ANS Refractometer (Salt) (1.000-1.030 SG)

Description

This model also includes a SG (specific gravity) scale and is perfect for measuring the salinity of marine aquariums.
A refractometer is a valuable tool for accurately determining salt content, surpassing a hydrometer in precision. The ppt (parts per thousand) and SG scales allow for effortless monitoring of your tank’s salinity, ensuring healthy fish. Divisions on the ppt scale indicate increments of 1 ppt, while the SG scale features 0.001 increments. It is specifically designed for measuring salt density in sea water and boasts a sturdy, corrosion-resistant brass construction.
For easy and precise readings, it has a high-contrast demarcation line and an easily adjustable zero line with a readily accessible screw.
